[bug-gettext] gettext.m4 and musl-libc

[Kylie McClain]

Hi,

I am trying to use the gettext built into musl-libc for programs
which use autoconf+automake for building. I know the program in
question (hunspell) supports musl's gettext, but the issue is that
whenever I run ./configure, it insists on using the included gettext,
rather than musl's built in gettext.

After talking to people on musl's IRC, it was determined that the
issue is that gettext.m4 has a bad check for if the libc has a
gettext implementation; namely, it only uses the libc's implementation
if the libc is glibc.

Could this be improved so that it works with musl's gettext?

Thanks.
