Re: [PATCH] Add to the 2.1.x branch GUILE_SITE_CCACHE_DIR and GUILE_EXTE

Subject: Re: [PATCH] Add to the 2.1.x branch GUILE_SITE_CCACHE_DIR and GUILE_EXTENSION_DIR Autoconf macros along with needed siteccachdir entry in pkgconfig file

I improved the commit log and the comments to make them better
formatted and more terse. Does the commit log look better?

I also made it so that pkgconfig is tried first for finding
site-ccache and only if that fails will the interpreter be used (the
messages say specifically which method they are using now). It is
definitely better to have both methods in there.
