This adds 3 new options to patch order:
* bundled + bundled_exp
* bundled + bundled_exp + local
* local + bundled + bundled_exp
The path for bundled experimental patches is: ${CT_LIB_DIR}/packages/${pkg_dir}/experimental
and patches that are still being reviewed, but not yet applied upstream
may be toggled with ENABLE_EXPERIMENTAL_BUNDLED_PATCHES.
Also fix modelines for editors on bootstrap and scripts/functions, and
fix mix whitespace in scripts/functions.

Picolibc needs two additional gcc build options so that libstdc++
works correctly. When building picolibc as a companion library, those
are added in do_cc_libstdcxx_picolibc, but when built with picolibc as
the main C libary, those need to be added in the main GCC build.

libgccjit is still under development and, despite its name, may also be used for
ahead-of-time compilation.
Documentation can be found on the gcc website:
https://gcc.gnu.org/onlinedocs/jit/internals/index.htmlhttps://gcc.gnu.org/wiki/JIT
With this change it's possible to enable the building of the libgccjit. It's
enabled as a language (with --enable-languages=jit) even if not a language
frontend at all.
The main changes are related to the requirement of having everything host side
built as Position Independent Code (PIC) with --enable-host-shared. GCC has the
needed logic for building its dependencies (mpc, gmp, mpfr, ...) correctly when
built "in-tree", which is not the case with crosstool-ng (see
https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=05048fc29f0)

When `CT_NEWLIB_NANO_INSTALL_IN_TARGET=y`, the `nano.specs` file
emitted by the newlib-nano build script contains an invalid include
path, resulting in the full `newlib.h` being included instead of the
nano `newlib.h` by the application.
`=/include/newlib-nano` is not a valid path (`=` does not mean anything
and that string is taken as an include path as-is) and GCC ignores this
include path, resulting in application including the `newlib.h` from
`include/` which contains the newlib build configurations for the full
newlib.
This commit modifies the newlib-nano build script to emit a proper
newlib-nano include path relative to the `GCC_EXEC_PREFIX`.

Previously, cc/gcc.sh assumed that liblto_plugin would always be

In Bryan Hundven's patch 1ad439907 from 2010, the author added -lstdc++
and -lm to the host gcc build's LDFLAGS, because at the time the linker
did not correctly include these libraries causing the build to fail.
In modern builds, this causes a problem for canadian gcc builds where
the host machine is mingw32-w64 Windows.
Within the gcc build there is the liblto_plugin module. On Windows this
must be built as the "liblto_plugin.dll" dynamic library. However,
libtool cannot produce a dynamic library unless every library dependency
is also a dynamic library, and falls back to producing a libstdc++.a
static library. liblto_plugin does not require libstdc++ - it
does not contain any C++ code, and the dependency would usually be
elided by the linker.
Unfortunately, in this case, crosstool-ng will never build a
libstdc++.dll dynamic library - only a libstdc++.a static library.
Therefore, there will never be a dynamic library version of stdc++ for
libtool to load and then discard.
This patch corrects the issue by removing "-lstdc++" from LDFLAGS,
because modern versions of gcc are able to correctly include libstdc++
where necessary. It also remove "-lm" for similar reasons.

After 557b9d4, libc_start_files and libc_main steps are performed one
after another. It doesn't make sense, especially since some of the libcs
(glibc, uClibc-ng) go to great lengths to first install start files in
the first step, libc_start_files, only to remove them immediately in the
second step, libc_main.
Current build steps also break in the xtensa newlib configurations, as
it needs to install the custom xtensa headers before building the libgcc
and after 557b9d4, the headers are not installed before libgcc is built
in pass-1.
Therefore, finish what 557b9d4 mentioned but did not do: move header
installation into a new step, libc_headers, and combine libc_start_files
and libc_main into a single step.
This also allows to combine the core pass-1/pass-2 steps, to be done in
a subsequent commit.
