pkgconfig bumpy?

[Chad Kittel]

Hello,

I thought i would shoot an email off to the ML here to see if there is
a reason why we shouldn't upgrade the pkgconfig module.  We currently
have 0.15.0, latest official one is 0.18.0.  However, I did some testing
around and found 0.18.0 to be problematic on a few random modules where
as the version prior to 0.18.0, 0.17.2 did not experience any
troubles.  Though looking at it again, that could be due to me just not
having the ENV variable set up right. (It looks like pkgconfig 0.18.0
went from PKG_CONFIG_PATH to just PKG_CONFIG)

Anyhow, The reason for this is because I'm ran into an application that
uses some autoconf stuff that needs features (scripts) found in the >=
0.17.0 release.  Looking around at other distros there seems to be a
good mix of both 0.15.0 or 0.17.2 being shipped, and no 0.18.0.

I propose we bump the module to 0.17.2.  Thoughts?

cheers,
Chad
