Possible addition to buildgroups.xml: pkg-config

[Andreas Thienemann]

Hi,

during a recent rebuild of all RHEL4 packages in mock, I saw a number of 
packages which expect pkg-config to be present during the build stage, but 
do not define it as a BuildRequire.

A short discussion of this issue on #fedora-devel suggested dropping 
pkg-config into the buildgroups.xml definitions, so that it gets installed 
by mock in each case.

Comments?

regards,
 andreas
