Ensure that msgfmt doesn't encounter problems during gcc bootstrapping.
Solves error messages like the following:
msgfmt: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/libstdc++.so.6)
The libgcc_s.so used during build doesn't satisfy the needs of the
libstdc++.so that msgfmt is linked against. On the other hand, msgfmt
is used as a stand-alone application here, and what library it uses
behind the scenes is of no concern to the gcc build process.
Therefore, simply invoking it "as usual", i.e. without any special
library path, will make it work as expected here.

When cross compiling a target gcc, target flags may be used on the host
Configure identifies a number of warning flags (WARN_CFLAGS and
WARN_CXXFLAGS) from the $CC value. The cross compiler may be different
from the host compiler and may not support the same set of flags. This
leads to problems such as:
cc1plus: error: unrecognized command line option "-Wno-narrowing"
cc1plus: error: unrecognized command line option "-Wno-overlength-strings"
Work around this problem by removing the warning flags from the
BUILD_CXXFLAGS value, in a way similar to the BUILD_CFLAGS.

Author: Timo Teräs <timo.teras@iki.fi>
Alpine musl package provides libssp_nonshared.a. We link to it unconditionally,
as otherwise we get link failures if some objects are -fstack-protector built
and final link happens with -fno-stack-protector. This seems to be the common
case when bootstrapping gcc, the piepatches do not seem to fully fix the
crosstoolchain and bootstrap sequence wrt. stack-protector flag usage.
