GCC emits the (undefined) instruction ffreep when TARGET_USE_FFREEP is set
(which happens when -mtune opteron or -mtune athlon is passed on the command
line.
As of the latest available build, Solaris' /usr/ccs/bin/as doesn't understand
this opcode and barfs.
The use of ffreep seems to have been introduced and discussed in this thread:
