[Bug-tar] GNU tar bootstrap fix to work around gnulib/gettext/autopoint confusion

[Paul Eggert]

I installed this into GNU tar.  The problem is that after tar's
bootstrap script sets up tar's source files by copying many of them
from gnulib, the autopoint command then overwrites some of the gnulib
.m4 files (from gettext I think).  This is a bit of a pain to
maintain.  Does anybody have an idea for fixing this more
systematically?

        Set LC_ALL=C so that file names sort consistently.
        Prefer the gnulib copies of gettext.m4, glibc21.m4,
        lib-ld.m4, lib-prefix.m4, po.m4 too.
