For now, last libjava alpha*-*-freebsd* configuration patch

[Loren James Rittle <rittle at latour dot rsch dot comm dot mot dot com>]

I have posted and applied all boehm-gc (simple) and libffi (trivial,
configuration enablement only) patches required for alpha*-*-freebsd*.

Ignoring, for the moment, the remaining FP issue on FreeBSD/alpha that
we have discussed over on the java list.  Most of the actual
configuration for *-*-freebsd* and alpha*-*-* in libjava is generic
enough to work as is.  This remaining trivial patch to address
non-standardization in the location and contents of <.../pal.h>
appears to be all required to allow bootstrap.  Even with the FP issue
hanging over this port, I propose to apply this patch since I believe
it is correct on its own.  After that, I will test all of the recent
*-*-freebsd* patches on the 3.1 branch and request to move them.

Fails to bootstrap alpha*-*-freebsd[45]* without patch.

	* include/posix-threads.h: Support <.../pal.h> on FreeBSD/alpha.
