So how do we feel about

Bad, as explained before. Instead, how about adding some pkgconfig files
which are generated during build and thus we have complete control over their
contents? Eg. the attached one to xemacs-devel:
$ pkg-config xemacs --modversion
21.5.28
$ pkg-config xemacs --variable=sitestartdir
/usr/share/xemacs/site-packages/lisp/site-start.d
$ pkg-config xemacs --variable=sitepkglispdir
/usr/share/xemacs/site-packages/lisp
$ pkg-config xemacs --variable=sitemoduledir
/usr/lib64/xemacs/site-modules
$ pkg-config xemacs --cflags
