Daniel Bertalan ae21002cb5 Toolchain+Ports: Update GCC to 13.2.0
This is a minor bugfix release, which to my knowledge contains nothing
of importance to us. However, there is one QoL change to our patches.

We no longer force `-fpic` in the compiler driver, and instead use the
`--enable-default-pie` configure option to generate position-independent
code suitable for executables. For building shared libraries, the
`-fpic` flag must be specified explicitly.

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.

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.

0007-libstdc-Build-static-library-with-fPIC.patch

libstdc++: Build static library with -fPIC

We want the libstdc++.a library to contain -fPIC code in order to link it statically into LibC/our shared objects. However, the build system forces no-pic/pie instead.

This hack is from https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58638
