Re: [sparc64/base-gcc] Fix build of audio/mpg123

It already did before.

The issue here is that upstream changed configure.ac to be compatible
with autoconf 2.71, then went back and used 2.69.

* With 2.71, AC_PROG_CC tries to enable C89/C99/C11 and AC_PROG_CC_C99
is a nop.
* With 2.69, AC_PROG_CC only tries to enable C89 and you need to use
AC_PROG_CC_C99 to get C99.

I prefer to let the configure script handle this as intended.
OK?
