PKG_CONFIG, if defined at all, should be the path to the pkg-config
binary, in case you for some reason need to use another than the one
normally found in your PATH. If you intend to use /usr/bin/pkg-config
(and why wouldn't you?), don't set PKG_CONFIG.

This is the default location where your /usr/bin/pkg-config looks for
.pc files, so this doesn't seem necessary either.
