[pacman-dev] [PATCH] libmakepkg: install pkg-config file

[Eli Schwartz]

Since makepkg exports a public library of functions, other projects may
wish to use these functions. Highlights include parseopts or our
messaging functions.

Install a pkg-config file in order to let downstream users detect where
they can source the libmakepkg functionality. This is useful e.g. to
gracefully handle the case where a thirdparty project is configured and
installed into a different datarootdir from pacman, but still wants to
use the installed pacman's version of libmakepkg.

pkgconfig.generate is bloat for this and results in useless keys
cluttering up the generated .pc -- there is no advantage of generating
it over configuring it, if we're not benefiting from library
autodetection.
