--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
The four operand form of the mtfsf instruction was added in Power ISA 2.5 and
gas recognizes it when targeting power6 or later.  From the glibc snippet it
does look like the first block controlled by _ARCH_PWR6 is missing the .machine
"power6" directive.  Once it's added I would expect as to be happy again (it is
in my tests, though I didn't go as far as building all of glibc).

365 # ifdef _ARCH_PWR6
366   /* Use the extended four-operand version of the mtfsf insn.  */
367   mtfsf  0xff,fp0,1,0
368 # else
369   .machine push
370   .machine "power6"
