xscale-elf-gcj status: looking good

[Anthony Green]

xscale-elf-gcj 3.1 is looking pretty good right now.  It all builds and the
testsuite runs with reasonable looking results (so far).

Only one GCC patch is necessary...

(1) This libjava testsuite fix:

    http://gcc.gnu.org/ml/java-patches/2002-q1/msg00786.html

Two other src patches are needed...

(2) This newlib patch adds a dummy fcntl system call:

(3) This simulator patch increases the default target memory to 8MB
    from 2:

I'll post full test results tonight or tomorrow.  

In any case, I think we're in a position to turn java language support
on by default for xscale-elf.  Other arm-elf like targets may be in
good shape also.  I'll run tests soon.

What do you think Nick?

BTW - I thought arm targets didn't use sjlj eh anymore, but it looks
like that's what is being configured.
