I tried this on powerPC, and ruby built fine.  I haven't tested
it much, but the things I tested seem to work fine.

I tried it on sparc64, and ruby didn't build.  The attempt
ended with:

cc -O -pipe   -fPIC -I. -I. -c version.c

Bus error (core dumped)

Bus error (core dumped)
1 error
*** Error code 2

Looking in the work directory, it seems the bus error came up
while running mini-ruby:

work/ruby-1.8.2/miniruby.core

gdb tells me:

Core was generated by `miniruby'.
Program terminated with signal 10, Bus error.

(gdb) backtrace full
#0  0x0000000040859d5c in __vfprintf () from /lib/libc.so.6

I noticed the other email message which talked about the settings
of CFLAGS, so I changed my /etc/make.conf
from:
      CFLAGS= -O -pipe
to:
      CFLAGS+= -O -pipe -g

This changed the resulting 'cc' commands
from:
       cc -O -pipe   -fPIC -I. -I. -c main.c
to:
       cc -O2 -fno-strict-aliasing -pipe -O -pipe -g   -fPIC -I. -I. -c main.c

This still core-dumps.  I wondered if it might be significant that
"something" wanted this to be -O2, but my CFLAGS was setting a -O.
So I moved the line for '.include <bsd.port.pre.mk>' such that it
was before any of the lines which set CFLAGS in the makefile  (I
put it right after GNU_CONFIGURE=yes).  That didn't change anything.
All the 'cc' commands came out the same, and mini-ruby core-dumped.

So then I tried commenting-out the setting of CFLAGS in my
/etc/make.conf file.  That gave me 'cc' commands of:

      cc -O2 -fno-strict-aliasing -pipe   -fPIC -I. -I. -c main.c

but it still just core-dumps.  I then tried to make it with DEBUG=yes,
and used gdb to step through it.  It does start in main, and it
executes several thousand instructions before it dies.
