libquadmath relies on libc presence (sqrt symbols).
When initial toolchain is bootstrapped libc is not
available yet.
The change disables libquadmath for bootstrap cases
when libc is not installed yet. gcc-stage2 still
uses platform defaults for libquadmath.

libquadmath is a small support runtime library for _Float128
types. sci-libs/fftw happens to use it and expects it to be
provided by gcc. Let's provide it unconditionally.

fixlafiles.awk can mangle two things in .la fils:
1. patch reference 'from .../libstdc++.la' to '-lstdc++'
2. change ${CHOST} when user switches CHOST and rebuilds the system
[1.] is not relevant since gcc-4 in Gentoo where we started deleting
libstdc++.la on gcc installation. Nothing should embed libstdc++.la
paths anymore.
[2.] is a rare one-off step that has a lot more caveats than just .la
file patching.
Generally .la files are tracked by package manager and should not be
changed after they are installed on disk. 'fix_libtool_files.sh' breaks
that invariant.
On top of that portage's FEATURES=fixlafiles removes nested .la files
references.
Let's remove 'fix_libtool_files.sh' and 'fixlafiles.awk' completely.
If really needed we can reintroduce it as a separate tool.

--enable-altivec does not do anything since gcc-4:
https://gcc.gnu.org/legacy-ml/gcc/2005-03/msg01091.html
The change drops passing of --enable-altivec for all gcc versions and
drops IUSE=altivec for gcc-10+.
Once gcc-10 is stable everywhere we can drop IUSE=altivec for all gcc
versions.

In bug #701786 'strip-flags' removed all unsafe options
first including -O3 and only then mangled -O? to -O2.
This effectively made gcc to compalie wth -O0, generated
huge slow profile and confused LTO.
Let's default to safer -O3->-O2 transition.

This reverts 'dosym' part of
"toolchain.eclass: Prepend/strip EPREFIX"
patch. portage-2.3.85 and above contains
"dosym: revert deprecated prefix compat (bug 615594)"
patch. That effectively breaks gcc's /usr/bin/ symlinks.

Before tha change toolchain_src_unpack() did not unpack every SRC_URI
entry and instead relied on toolchain_src_unpack() to unpack only
needed tarballs. Any special handling was only needed for old USE=d
versions of gcc.
This change moves all source code mangling to src_prepare() and makes
toolchain_src_unpack() a default_src_unpack().
The only exception is ebuild users of 'GCC_A_FAKEIT' (dev-lang/gnat-gpl)
who have to use it to workaround non-standard behaviour of toolchain_src_unpack()
The change will allow dev-lang/gnat-gpl to migrate to default_src_unpack().

on ppc64 gcc assumes the following:
from gcc ppc64 manual:
-mabi=elfv1
Change the current ABI to use the ELFv1 ABI. This is the default ABI
for big-endian PowerPC 64-bit Linux. Overriding the default ABI
requires special system support and is likely to fail in spectacular
ways.
-mabi=elfv2
Change the current ABI to use the ELFv2 ABI. This is the default
ABI for little-endian PowerPC 64-bit Linux. Overriding the
default ABI requires special system support and is likely to
fail in spectacular ways.
Since we are taking gcc defaults, let's pass --with-abi=elfv2 on musl
targets
without it it will fail, since musl does not support elfv1 at all.
from musl INSTALL file:
* PowerPC64
* Both little and big endian variants are supported
* Compiler toolchain must provide 64-bit long double, not IBM
double-double or IEEE quad
* Compiler toolchain must use the new (ELFv2) ABI regardless of
whether it is for little or big endian
