72051f7036 rules.mk: export TMPDIR
Set TMPDIR to the same value as the existing TMP_DIR variable in order to
let gcc and various other utilities use the local temporary directory
instead of the system-wide one.

rules.mk: make PKG_CONFIG_DEPENDS properly track string values
The confvar macro is adjusted to not only consider if a variable has a
value or not, but also the value itself. Instead of creating a string of
'y' and 'n' characters, all variable names and values are concatenated
and hashed.

202ae4cc6a build: Pass -iremap gcc option as a single argument
Passing -iremap argument separately causes problems with projects that
use scons and its ParseFlags function. Consider this SConscript
example:

    env = Environment()
    d = env.ParseFlags("-iremap one:two")

ParseFlags will interpret one:two as a file name and the returned dict
d will contain only "-iremap". When the -iremap is passed to the
compiler without an argument, compilation obviously fails.

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.

7a315b0b5d build: implement make check and make package/X/check
This is intended to be used for a wide array of package sanity checks.

The first check that is implemented is for the hash of downloaded files.
It checks:
  - Missing hash
  - Use of SHA256 instead of MD5
  - dl/<file> hash not matching hash in makefile
  - deprecated MD5SUM variable

The deprecated MD5SUM variable check is skipped for feeds/ until OpenWrt
is updated as well

27854a0a84 build: add checksum target
Add a new "checksum" make target which generates an sha256sums file over the
image files produced in bin/targets/ and automatically call it during make
world after the package index generation.

The advantage of this new target is that it is guaranteed to run after the
images, the SDK and the ImageBuilder archives have been generated to ensure
that they all end up in the checksum file. Fixes FS#51.

Uses sed to postprocess the OpenSSL digest output into an sha256sum command
compatible format.

3bbb927728 build: Allow kernel modules to set build ID debug symbol
This change adds support for specifying a build ID for kernel modules.
This is done by setting PKG_BUILD_ID to a hexadecimal string, which will
then be passed to the kernel linker. In addition, when this flag is set,
the build ID debug symbol (.note.gnu.build-id) will not be stripped from
the kernel module. This symbol is exported in sysfs by the kernel (if
the kernel is compiled with CONFIG_KALLSYMS) and so can be used to
uniquely identify a version of a kernel module in a running kernel. This
is useful for keeping track of different versions of a module when doing
experiments and development.

Modules that specify the build ID will be ~100 bytes larger (depending
on the length of the build ID specified). There is no size difference
for kernel modules that do not set this variable.

9a46799804 build: use gcc-provided ar, nm and ranlib where appropriate
Since GCC 4.7, GCC provides its own wrappers around ar, nm and ranlib, which
should be used for builds with link-time optimization. Since GCC 4.9, using them
actually necessary for LTO builds using convenience libraries to succeed.

There are some packages which try to automatically detect if gcc-{ar,nm,ranlib}
exist (one example is my package "fastd" in the package repository, which tries
to use LTO). This breaks because the OpenWrt build system explicitly sets the
binutils versions of these tools.

As it doesn't cause any issues to use gcc-{ar,nm,ranlib} instead of
{ar,nm,ranlib} even without LTO, this patch just makes OpenWrt use the
GCC-provided versions by default, which fixes the build of such packages with
GCC 4.9.

(I know that builds fail though when clang is used with -flto and
gcc-{ar,nm,ranlib}, but as all OpenWrt toolchains are based on GCC, this isn't
a real issue.)

Completely cleaning the tree (or at least `make clean toolchain/clean`) is
necessary to get a consistent state after the binutils plugins support patch and
this one (as trying to use gcc-{ar,nm,ranlib} with a binutils built without
plugin support will definitely lead to a build failure).
