It looks like it may be specific to my linux target
(mips-mti-linux-gnu).  With my elf target (mips-mti-elf), I do not get
the error.

Here is the error I get when running the testsuite with -msoft-float,
adding -msym32 to the option list will make the problem go away. Adding
-fno-pic to the options does not fix the problem.
