pkg.m4 patch

[Erik de Castro Lopo]

Hi all,

Please consider the following patch which improves reporting of
failures when package modversions don't match.

For instance using:

    PKG_CHECK_MODULES(VORBIS, vorbis >= 1.2.1,
             ac_cv_vorbis=yes, ac_cv_vorbis=no)

a failure due to mismatched versions will simply print:

   checking for vorbis ... no

with the patch results in an improved message:

    checking for vorbis >= 1.2.1 ... no

which is much easier for the end user to debug and which hence results
in less emails to me.

Patch follows.

Cheers,
Erik
