gdb/hpux-threads on HPPA

[H.Merijn Brand]

I finally took the time to make gdb-6.3 compile on HP-UX 11.00

This is probably not the way *you* might prefer the patch to be applied, but
without it, it won't compile

HP-UX 11.00 with gcc-4.0.0/64

I happen to have a ncurses 64bit lib that gdb finds, but does not like:

gcc64 -B/usr/local/pa20_64/bin -mpa-risc-2-0 -g -O2   -Dvfork=fork     \
        -o gdb gdb.o libgdb.a \
           ../bfd/libbfd.a ../readline/libreadline.a ../opcodes/libopcodes.a  
../libiberty/libiberty.a     -lncurses -lm  ../libiberty/libiberty.a
libgdb.a(hppa-hpux-tdep.o): In function `hppa_hpux_som_find_global_pointer':
: undefined reference to `som_solib_get_got_by_pc'

: undefined reference to `__getcury'
libgdb.a(tui-winsource.o): In function `tui_show_source_line':
: undefined reference to `__getcury'
collect2: ld returned 1 exit status

When run by hand with -lcurses, I get 

a5:/pro/3gl/GNU/gdb-6.3/gdb 160 > gcc64 -B/usr/local/pa20_64/bin -mpa-risc-2-0

I had to add

CORE_ADDR
som_solib_get_got_by_pc (CORE_ADDR addr)
{
  return (pa64_solib_get_got_by_pc (addr));
}

to pa64solib.c
