  I just reverted to what was already in place, but I agree, and
would prefer to remove gratuitous bash'isms.

  You mean, it creates a XORG_sdkdir shell variable?
My reading of m4 cannot find it in pkg.m4 (maybe I did not look
carefully enough ...) That would be very useful indeed to replace
the current calls.

  It is just illogical what it prints. If the problem is that
there may be too much things to print, it could just put print
something different, like:
Checking for required pkg-config modules...

  When possible I have been using $(XORG_CFLAGS), but did not
want to "gratuitously" do a s/@(\w+)@/$(\1)/g in Makefile.am's...
but it could be a good thing to do, mainly for consistency.
