__USER_LABEL_PREFIX__
This macro expands to a single token which is the prefix applied to user
labels (symbols visible to C code) in assembly. For example, in the m68k-aout
environment it expands to an `_', but in the m68k-coff environment it expands
to nothing.
This macro will have the correct definition even if -f(no-)underscores is
in use, but it will not be correct if target-specific options that adjust this
prefix are used (e.g. the OSF/rose -mno-underscores option).
