mono build problem

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

lang/mono builds properly on a -current/amd64 box. I have now tried two
-current/i386 boxen, one xeon with pkg_comp, the other sempron directly
with "make" in pkgsrc, and lang/mono fails with:

...
echo '#! /bin/sh' > _tmpinst/bin/gmcs ; \
r=`pwd`; m=`cd /pkg_comp/obj/pkgsrc/lang/mono/default/mono-2.10.2/mcs && pwd`; \
echo 'exec "'"$r/_tmpinst/bin/mono"'" "'"$m/class/lib/net_2_0/gmcs.exe"'" "$@"' 
>> _tmpinst/bin/gmcs ; \
chmod +x _tmpinst/bin/gmcs
...

The core dump is mcs/mono.core, but not many clues there:
Core was generated by `mono'.
Program terminated with signal 6, Aborted.
#0  0xbbb99857 in ?? ()

Just odd that amd64 vs i386 seems to matter (all try to build mono-2.10.2nb3
with gcc 4.5.3)
