Subject: [PATCH] Install a pkgconfig .pc file. This allows external plugins to
 find where the header file is located, where Hexchat expects to find plugins
 so it can load them at startup and which version of Hexchat is installed. The
 path where pkgconfig files are stored is determined by a macro available in
 newer versions of pkgconfig which can be overridden by the --with-pkgconfig=
 configure switch. However, if this macro is unavailable (older versions of
 pkgconfig) then m4ifdef will make it fallback to simply use
 ${libdir}/pkgconfig (which is the default).
