building libgcj on irix 6.5

[Jeff Sturm]

I've seen the same thing happen on other platforms... it appears to be
due to the new setjmp/longjmp exceptions, but I haven't completely
figured it out yet.  If you do a "nm libgcj.so.1 | grep Throw" I think
you'll see _Jv_Throw is absent and _Jv_SjljThrow is defined instead...

You might get a successful build with --disable-sjlj-exceptions.
