[Bug c/26607] New: Illegal inlined assembler on config/rs6000/darwin-ldouble.c

["edmar at freescale dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Gcc cannot process in-lined assembler, when configured for powerpc-gnuspe
target (Note: that target does not have float point registers, but it has float
point sinstructions that operates on the general purpose registers).
