[Debian GNUstep maintainers] gnustep-base and libffcall

[Yavor Doganov]

Now that libffi is preferred upstream:

2008-07-01  Richard Frith-Macdonald <rfm at gnu.org>

        * configure.ac: use libffi in preference to ffcall as it doesn't mess
        up the stack.

gnustep-base/1.16.3-1 got built against libffi on all arches (I think,
but didn't check thoroughly) -- still has to be built on alpha and
sparc, but I guess the build will be successful.

Should we get rid of the -libffi packages and make libffi the default
everywhere?  FWIW, I've been using them on i386 and powerpc since
Hubert introduced them, without any problems.
