[MPICH] ch3:sctp configure broken

[Steve Kargl]

It appears that configuring the ch3:sctp device is broken
on FreeBSD.  With mpich2-1.0.5p4, I see

sourcing /usr/tmp/mpich2-1.0.5p4/src/mpid/ch3/setup_device
RUNNING SETUP_DEVICE FOR THE CH3 DEVICE
sourcing /usr/tmp/mpich2-1.0.5p4/src/mpid/ch3/channels/sctp/setup_channel
RUNNING SETUP_CHANNEL FOR THE SCTP CHANNEL

checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.
configure: error: Configure of src/mpid/ch3 failed!

Using nemesis seems to work except that it causes random nodes
in my cluster to reboot.
