Stick with AC_CHECK_LIBS, see reasons below.

AFAIK, pkg-conifg quite sucks. If you use autotools, you should rely on
libtool since the current pkg-config autotools support is quite
unsatisfactory (especially regarding to other languages that C and cross
compiling) . Writing and maintaining custom m4 macros is usually a
nightmare, this is why pkg-config was created.

That's how I see it, maybe I am wrong.
