614a420084 kernel: use KCFLAGS for passing EXTRA_OPTIMIZATION flags
This uses kernel's generic variable and doesn't require patching it with
a custom Makefile change. It's expected *not* to change any behaviour.

b993b68b6c build: introduce $(MKHASH)
Before this commit, it was assumed that mkhash is in the PATH. While
this was fine for the normal build workflow, this led to some issues if

    make TOPDIR="$(pwd)" -C "$pkgdir" compile

was called manually. In most of the cases, I just saw warnings like this:

    make: Entering directory '/home/.../package/gluon-status-page'
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    [...]

While these were only warnings and the package still compiled sucessfully,
I also observed that some package even fail to build because of this.

After applying this commit, the variable $(MKHASH) is introduced. This
variable points to $(STAGING_DIR_HOST)/bin/mkhash, which is always the
correct path.

af22991e03 build: make sure asm gets built with -DPIC
Fixes issue openwrt/packages#14921, whereby inline ASM wasn't getting
built as PIC; look at gmp-6.2.1/mpn/x86/pentium/popcount.asm for

ifdef(`PIC',`

that it gets quoted where necessary (such as setting environment

ddab795b37 rules: fix empty COMMITCOUNT/AUTORELEASE
Packages that are in-tree only often lack a PKG_VERSION and only use the
PKG_RELEASE to mark changes. Using COMMITCOUNT/AUTORELEASE variables
causes an issue as both variables are empty during the metadata DUMP
phase.

Instead of leaving these variables empty and causing an error message
like below, set the variables to 0 during dumping. On actual building
the variable is evaluated causing in a value above 0.

513f7171a3 rules: fix COMMITCOUNT logic
The newly added $(COMMITCOUNT) variable was wrongly increased by plus
one. The addition should have been only added to $(AUTORELEASE) as
OpenWrt traditionally starts counting at one rather than zero.

$(AUTORELEASE) counts the commits since the last bump, which is zero on
the version bump commit itself.

This commit increases $(AUTORELEASE) by one while leaving $(COMMITCOUNT)
as is.

The base-files package is the only package using $(COMMITCOUNT) so far
and requires a pseudo commit to keep the PKG_RELEASE correct. A non
functional change (Copyright bump) is done in the next commit.

9ae3c6f94c rules: add AUTORELEASE and COMMITCOUNT variables
The lack of bumped PKG_RELEASE variables is a recurring theme on the
mailing list and in GitHub comments. This costs precious review time,
a rare good within the OpenWrt project.

Instead of relying on a manually set PKG_RELEASE this commit adds a
`commitcount` function that uses the number of Git commits to determine
the release. The function is called via the variables `$(AUTORELEASE)`
or `$(COMMITCOUNT)`. The `PKG_RELEASE` variable can be set to either of
the two.

- $(AUTORELEASE):

Release is automagically set to the number of commits since the last
commit containing either ": update to " or ": bump to ".

Example below:

    $ git log packages/foobar/
    foobar: fixup file location
    foobar: disable docs
    foobar: bump to 5.3.2
    foobar: fixup copyright

Resulting package name: foobar_5.3.2-3_all.ipk, two package changes
since the last upstream version change, using a 1 based counter.

- $(COMMITCOUNT):

For non-traditional versioning (x.y.z), most prominent `base-files`,
this variable contains the total number of package commits.

The new functionality can also be used by other feeds like packages.git.

In case no build information is available, e.g. when using release
tarballs, the SOURCE_DATE_EPOCH is used to have a reproducible release
identifier.

0eb2fa39f3 rules.mk: use -fPIC instead of -fpic on arm64
Some packages fail to build on arm64 when PKG_ASLR_PIE_ALL=y, due to
machine-specific size restrictions on the global offset table.
While the manual instructs to recompile with -fPIC if it fails with
-fpic, by doing this per package, there is still a risk of random
breakage due to version bumps or other changes, so let's use -fPIC on
arm64 by default.

While comparing the sizes of 141 packages built with -fpic vs -fPIC,
most packages are either equal or smaller in size. Only 9 of the
compared packages turned out slightly larger.

Drop our local sstrip copy and use the current ELFKickers upstream

Patch the original makefile in order to avoid building elftoc, since it

9e7ef46065 tools: add fakeroot
SELinux support requires setting the appropriate SELinux security context
to files and directories, which needs to happen at build time in order
to support read-only root filesystem scenarios. In order to create these
security contexts, we will have to run some SELinux-specific tools on
the host machine, but that requires root access. This adds support for
fakeroot, which the build process will use to run the SELinux security
context creation and the image creation.

eb155f755a build: make prefix mapping of debug information optional
Remapping the local build path in debug information makes debugging
using ./scripts/remote-gdb harder, because files no longer refer to the full
path on the build host.

For local builds, debug information does not need to be reproducible,
since it will be stripped out of packages anyway.

For buildbot builds, it makes sense to keep debug information reproducible,
since the full path is not needed (nor desired) anywhere.

2ca084ccaa build: improve ccache support
Set CCACHE_DIR to $(TOPDIR)/.ccache and CCACHE_BASEDIR to $(TOPDIR).
This allows to do clean and dirclean. Cache hit rate for test build
after dirclean is ~65%.
If CCACHE is enabled stats are printed out at the end of building process.
CCACHE_DIR config variable allows to override default, which could be useful
when sharing cache with many builds.
cacheclean make target allows to clean the cache.

Changes from v1:
- remove ccache directory using CCACHE_DIR variable
- remove ccache leftovers from sdk and toolchain make files
- introduce CONFIG_CCACHE_DIR variable
- introduce cacheclean make target

1f0063b58c rules.mk: remove "$(STAGING_DIR)/include"
"$(STAGING_DIR)/include" was carried over from buildroot-ng to OpenWrt
in commit 60c1f0f64d. buildroot has
dropped this directory a long time ago.

In OpenWrt the directory is still created by the PrepareStaging macro
and is part of the default TARGET_CPPFLAGS. But nothing at all installs
headers into this directory, nor should anything be installed under this
path.

Removing this directory from TARGET_CPPFLAGS will cut down the log noise
a bit. Not only will CPPFLAGS be shorter, there will be less warnings
set off by "-Wmissing-include-dirs" (or even failures when paired with
"-Werror"). After all the directory does not even _exist_ in the SDKs,
which are used on the build bots when building packages (see [1] and
[2]).

But there's a few things wrong with this approach,

57657a7237 build: Suffix build directory with _$(LIBC) for external toolchains
For external toolchain, we also know the type of C library used, and the
toolchain triplet may not always be reflective of that, therefore make
$(TARGET_DIR_NAME) suffixed with _$(LIBC).

7d57db4d9b build: introduce STAGING_DIR_IMAGE
Introduce a new location STAGING_DIR_IMAGE which is intended to be used by
bootloader iamges and similar image-related artifacts.

This directory is guaranteed to be persistent across kernel upgrades which
might involve a removal of KERNEL_BUILD_DIR and is guranteed to be bundled
with the image builder.

build: move STAGING_DIR_HOSTPKG and BUILD_DIR_HOST back to a common directory for all targets
Using a single host package staging dir (and build dir) significantly speeds up
builds when multiple targets are built in succession, especially for large host
packages like NodeJS.

$(STAGING_DIR)/host is kept in addition to $(STAGING_DIR_HOSTPKG) in most
places; it is still used as destination for host files in Build/InstallDev.
