Yes, privately I arrived at the exact same fix when I switched to an
hpux variant.

The reason I couldn't reproduce it initially is that pa-linux-gnu
doesn't uses pa.c:output_ascii.  Instead I think its macro
ASM_OUTPUT_ASCII has inline code which has subcalls to
ASM_OUTPUT_LIMITED_STRING from elfos.h.  Both of those macros had the
unsigned char issue dealt with correctly which masked the problem for
me.

Anyway, sorry for introducing the problem.
