+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.

+"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."
