This is a mostly straight-forward rebase of our patches on top of 13.1.0. The spec files needed a change, as GCC no longer supports STABS debug information, but we were building GCC with support for it. Highlights of this release include static `operator()`, The Equality Operator You Are Looking For and extended `constexpr` support. |

Patches for gcc on SerenityOS
0001-Add-a-gcc-driver-for-SerenityOS.patch
Add a gcc driver for SerenityOS
This patch adds support for the *-*-serenity target to gcc.
It specifies which flags need to be passed to the linker, defines the
serenity macro, sets the correct underlying type of size_t and
ptrdiff_t, and enables IFUNCs.
0002-fixincludes-Skip-for-SerenityOS-targets.patch
fixincludes: Skip for SerenityOS targets
fixincludes is responsible for fixing mistakes in system headers that
rely in compiler extensions that GCC doesn't support or cause errors in
C++ mode.
Our headers don't have such problems, so this hack is of no use for us.
0003-libgcc-Build-for-SerenityOS.patch
libgcc: Build for SerenityOS
This patch enables building gcc's own C runtime files, and sets up exception handling support.
0004-libgcc-Do-not-link-libgcc_s-to-LibC.patch
libgcc: Do not link libgcc_s to LibC
The toolchain is built before LibC, so linking to the C runtime library would fail.
0005-i386-Disable-math-errno-for-SerenityOS.patch
i386: Disable math errno for SerenityOS
SerenityOS uses exceptions for math error handling, which allows the compiler to do more optimizations on calls to math functions. This patch has the effect of setting -fno-math-errno by default.
0006-libstdc-Support-SerenityOS.patch
libstdc++: Support SerenityOS
During the toolchain build, SerenityOS libraries are not available, so we have to manually tell libstdc++ about what our LibC supports.
In most places, we take the Newlib code paths.
