Listen guys, you may not like this behavior, but it's not a bug.
If you read the makefile standards, it's to allow a package to be
installed into a different location at "make install" time.

There definitely shouldn't be any PKG_CONFIG_PATH special case
handling for anything in grc_<component_name>.m4.

A ton of effort was put into making the building system work reliably
and consistently (mostly by Michael Dickens).  A lot of the details
are quite subtle, and the effort took a long time to stabilize, and
has proven itself to work on a wide variety of OS's and distributions.
All of the grc_<component_name>.m4's should follow the same pattern.
There shouldn't be any divergence in the boilerplate.

I removed the offending code because it was causing my build to break,
and noticed at that time that it shouldn't have been there in the
first place.
