[PATCH] cgit.mk: do not rely on pkg-config

[Jason A. Donenfeld]

If pkg-config is not installed, but Lua vanilla is forced, then we might
be able to get away with just padding "-llua". Unlike LuaJIT, headers
are normally installed to /usr/include, and the libs are usually
installed to /usr/lib and the headers to /usr/include, so we let the
compiler eventually have success or error out.

What do you guys think of doing this? Some people don't have
pkg-config... or something? Not sure if this is the best approach but...
