Link libffi as convenience library

[Bryce McKinlay <bryce at albatross dot co dot nz>]

We were bringing in ffitest.lo from libffi. This resulted in amusing
behaviour when the "--main" flag to gcj was omitted, because there was
a main() in libgcj itself. This patch builds a libffi convenience
library which only contains the proper code, fixing the problem.

	* Makefile.am: Make a libtool convenience library.

	* Makefile.am (libffi_files): Removed.
	(libgcj.la): Link libffi as a convenience library instead of 
	refering to its object files directly.
