* Modifications like adding @SSL_CFLAGS@ to .pc.acr files that
would be overwritten by `make pkgcfg` have been moved to
Makefiles proper.
* Missing .pc.acr files for libraries r_egg and r_crypto were
added to the tree as well as the configure script.
* Instead of explicitly listing every -lr_* library in every
.pc file in the Libs: section, r_* libraries are now listed
in the Requires: section, which ensures that flags get
transitively propagated. This gets rid of the MAGICSED hack.
