I added those options because that is the combination that initially
tripped the failure months ago. Then last week someone spotted
that mingw failed to build. Mike Frysinger and I have been trying to
come up with a configure solution that handles mingw not supporting
dv-sockser.o and some simulators always requiring it.

I don't think that's really much of an issue. Except to increase my 
build time.

I have a fix in my local tree and posted it to the list. Here is my test 
plan.

I regenerated all of the sim directories where configure.ac includes 
acinclude.m4.
That resulted in the following set of modified files on my working git 
branch:

#    modified:   bfin/configure
#    modified:   common/acinclude.m4
#    modified:   cris/configure
#    modified:   frv/configure
#    modified:   iq2000/configure
#    modified:   lm32/configure
#    modified:   m32r/configure
#    modified:   m68hc11/configure
#    modified:   mips/configure
#    modified:   mn10300/configure
#    modified:   sh64/configure

Based on that, I put together the following list of targets:

bfin-elf
cris-elf
frv-elf
iq2000-elf
lm32-elf
m32r-elfle
m68hc11-elf
mips-elf
mipstx93-elf
mn10300-elf
sh64-elf

For each of those targets, I will build with no sim-hardware argument,
--enable-sim-hardware, and --disable-sim-hardware. If the configure
and make complete successfully, I will run make check.

Any other suggestions on how to test this?
