PATCH: libjava FreeBSD configuration

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

OK, with this patch and the related GC patch (just posted under
separate cover), I now see only this expected set of 4 deterministic
failures (in both fully bootstrapped mainline and 3.1 trees on
i386-*-freebsd4.5):

FAIL: Throw_2 execution from source compiled test
FAIL: Throw_2 execution from bytecode->native test
FAIL: Throw_2 -O execution from source compiled test
FAIL: Throw_2 -O execution from bytecode->native test

And a varying small set of these non-deterministic failures:

WARNING: program timed out.
<random built executable>

There is no obvious correlation from one libjava `make check' to the
next regarding which exact test cases will get hit.  The most I have
seen is six out of 452 execution tests.  All three live cases I have
caught under gdb have this consistent backtrace (to look at it
further, I will need to rebuild the system ld-elf.so with debugging
enable):

(these random startup hangs were also seen before the GC patch with
the exact same backtrace thus I conclude that it is an independent
issue to be fixed if possible before the gcc 3.1 release)

Permission to apply to mainline?  Since it is a self-contained
configuration patch which affects only one port and improves it over
the generic per-CPU configuration, permission to apply to 3.1 branch
as well?

Loren
