soft-fp: Use __label__ for all labels within macros.
soft-fp has various macros containing labels and goto statements.
Because label names are function-scoped, this is problematic for using
the same macro more than once within a function, which some
architectures do in the Linux kernel (the soft-fp version there
predates the addition of any of these labels and gotos). This patch
fixes this by using __label__ to make the labels local to the block
with the __label__ declaration.
Tested for powerpc-nofpu that installed stripped shared libraries are
unchanged by this patch.
* soft-fp/op-common.h (_FP_ADD_INTERNAL): Declare labels with
__label__.
(_FP_FMA): Likewise.
(_FP_TO_INT_ROUND): Likewise.
(_FP_FROM_INT): Likewise.
