To build 32 bit appears to require
bsd_x86_32.s
to be set up along the lines of the macosx-port one.
It seems to have a problem where a preprocessor check keeps it from defining
.type, however a .type is always included farther on.
I believe the macosx-port version could just be dropped in.
However, I changed the bsd-port version like this...
cd hotspot
hg diff src/os_cpu/bsd_x86/vm/bsd_x86_32.s

Now I'm afraid the 'but'. This builds but the generated crashes.

I currently have no idea on that?
