[fedora-arm] libffi F15 SNAFU

[Andrew Haley]

The libffi package update that I did had a nasty side-effect: it bumped
the soname to libffi.so.6.  This is an incompatible change to Fedora 15,
and after some negotiation with the libffi maintainer I'm building a
new RPM that reverts the change back to libffi.so.5.  I'm also rebuilding
OpenJDK against this libffi update.

I'm hoping that no-one will be affected by this.  I'll let y'all know
when it's done.

Andrew.
