	Some changes to fix build problems in FreeBSD and Windows.

	* configure.ac: Added missing m4 defines specifying version numbers,
	and tests for libdl and libm (sets DL_LIB and MATH_LIB respectively).

	* babl.pc.in: Replaced several hard-coded items with ones defined
	when configure is run.

	* babl/base/Makefile.am:
	* extensions/Makefile.am:
	* tests/Makefile.am: Use $(DL_LIB) and $(MATH_LIB) instead of
	hard-coded options.
