Change reference in asm code from `__mcount'' to `___mcount'', to be

consistent with the (default) prepending of underscores to identifiers.

Because this reference is inside an ASM string it's too hairy to
conditionalize to support different toolchains that don't prepend underscores.
(Just don't do profiling with  such  toolchains.)
