-
-in gcc-8 -static means static non-pie, even if -pie or -static-pie
-are specified, -static-pie can be used to build static pie.
-
-in musl toolchains -static -pie always meant static pie, so this
-patch fixes the link specs accordingly, the new -static-pie is just
-an alias to -static -pie.

-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

-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.
