coreutils: Add code to consider musl when selecting charsets

The real issue is in gnulib where it should be fixed
but gnulib gets imported in source into various components
and that may take a while. So lets fix the componnets versions
and as/if they land in new gnulib with a fix we can take
it off.

+Subject: [PATCH] Unset need_charset_alias when building for musl
+
+localcharset uses ac_cv_gnu_library_2_1 from glibc21.m4
+which actually shoudl be fixed in gnulib and then all downstream
+projects will get it eventually. For now we apply the fix to
+coreutils
