-mcpu=cell is a valid option.

Do you mean that having `sysdeps/powerpc/powerpc[32|64]/cell' rather
than `sysdeps/powerpc/powerpc[32|64]/ppc-cell-be' is the problem?

The CELL PPE has a different cache and pipeline topology than the
Power6 even though they both implement the 2.05 ISA so its own
optimization is warranted and desired by some.
