configure: deal with non-standard libffi installations.
This addresses a failure to build with libffi on
Arch Linux, reported by Joe Eib.
* Makefile (opt/ffi.o, dbg/ffi.o): Pull LIBFFI_CFLAGS
into TXR_CFLAGS for just these object files.
* configure (have_pkgconfig, libffi_cflags): New variables.
(gen_config_make): Create new Makefile variable,
LIBFFI_CFLAGS, from libffi_cflags.
New configure test to detect pkg-config.
Libffi test falls back on using pkg-config to test for
existence of the library and to get the cflags and ldflags.
Any needed cflags end up in LIBFFI_CFLAGS and are used
only when compiling ffi.c.
