[Bug target/15334] New: ICE building libgcc/./_mulvsi3.o


Create a combined tree, as per <URL:http://gcc.gnu.org/simtest-howto.html>
of date "Mon May  3 23:42:42 UTC 2004".  Configure with the option
--target=m68hc11-unknown-elf (simtest-howto also lists other options I strongly
believe are redundant).  Build with "make all".  Observe the build failing:
