Actually, the problem that I'm currently seeing is:

/tmp/cc6v0Red.s: Assembler messages:^M
/tmp/cc6v0Red.s:26: Warning: No .cprestore pseudo-op used in PIC code^M
/tmp/cc6v0Red.s:26: Warning: Macro instruction expanded into multiple instructions^M

My intention is to get the testsuite working properly for the sde-elf target as well.
