27cb8d0e73 After a recent WARNS= bump on ld.elf_so it fails to build on hppa, 
complaining that we're "discarding qualifier from pointer target
type".

Use const char * instead of caddr_t to avoid the warning and get
distribution building on hppa again.

- look in src/compat/lib/libc for libc_pic.
- define RTLD_ARCH_SUBDIR to "i386" or "sparc" for amd64 and sparc64
  builds, respectively
if RTLD_ARCH_SUBDIR is defined, add this path before
RTLD_DEFAULT_LIBRARY_PATH in the default search path.

38bdc8954f Refactor common code to _rtld_relocate_plt_object to i386 and arm so they 
act like the other versions.
In _rtld_bind, if the result is 0, call _rtld_die.
Initialize _rtld_sym_zero.st_value to -_rtld_objself.maprelocbase.  Now when
the symbol is resolved, st_value + maprelocbase will equal 0 and the above
check in _rtld_bind will fire and a call to NULL will be avoided.

9cb7d16b11 Similar to other rela platforms, do not use any GOT entries (other than the 
first entry, which is a special case) in rtld_start, because they could be
all 0s.  Instead we use the difference between the real _DYNAMIC address
(which we can determine on 68k with a "lea (%pc,_DYNAMIC),..." and the
base-relative one (at the beginning of the GOT) to figure out the relocation
offset.

Not needed for binutils-current, but I might as well fix it now.

eea1001a73 Adjust for the fact that the GOT is all 0s in new binutils -- do the trick of
