A similar warning appears on i686-pc-linux-gnu.  I submitted a
patch earlier to eliminate this warning on i686-pc-linux-gnu by
changing the format string to use %u, and casting within the
macro.  I did this because all other users of this macro call it
with 0 or an unsigned int.  And, furthermore, the
ASM_GENERATE_INTERNAL_LABEL macro, which should generate the same
label name, already uses %u and performs the cast (in elfos.h, at
least).
