Problem is that the assembler name might or might not be prefixed by '*'

The change is just to fix wrong warning because the current
implementation
of TARGET_SET_CURRENT_FUNCTION /always/ skips the first char when the
assembler name is set.
FWIW, there's default_strip_name_encoding (varasm.c), which does the same
thing, and is used by a couple of other targets.
Yes, I know.
But I would prefer targetm.strip_name_encoding then, even though avr does
not implement it.
I'm prefer `targetm.strip_name_encoding' or `default_strip_name_encoding'.
May be `default_strip_name_encoding' is better because it's used in few ports.
Denis.
So here is the revised version of the patch.
