Without this tag, executables that link libgcc_s.so.1, which is every
executable, end up with the host path to libgcc_s.so.1 as the path for
the dynamic dependency (DT_NEEDED) of the executable. By making sure
that the libgcc_s.so.1 shared object includes the DT_SONAME tag, the
path to libgcc_s.so.1 dynamic dependency will only contain the basename,
instead of the absolute host path.
There was a typo in one of the spec files which resulted in us not
building softfp support for libgcc. Additionally we were missing flags
to build libgcc_s. This patch also makes sure we're not trying to
link against crtbeginS.o and crtendS.o. This is part of a larger effort
to at least get the userland to build at all.
This shouldn't cause any breaking changes, so a toolchain rebuild is not
required.
As per Hendiadyoin's request, math errno is disabled by default, which
should enable some extra compiler optimizations in LibGL and LibSoftGPU
code that uses math functions heavily.
