ppc64_linux_convert_from_func_ptr_addr broken

- Subject: ppc64_linux_convert_from_func_ptr_addr broken
ppc64_linux_convert_from_func_ptr_addr is broken in many ways:
- despite its name get_target_memory_unsigned does not read memory, but
section contents, thus it will return some unrelocated value instead of
the real memory contents.
- target_section_by_addr also matches unrelocated section addresses, thus
can return a section that has nothing to do with the running process.
I get much better results when reverting the function to the state before
this commit:
2003-10-24 Andrew Cagney <cagney@redhat.com>
* target.c: Include "gdbcore.h".
(get_target_memory, get_target_memory_unsigned): New functions.
* target.h (get_target_memory, get_target_memory_unsigned): Declare.
* ppc-linux-tdep.c (ppc64_linux_convert_from_func_ptr_addr):
Use get_target_memory_unsigned.
* Makefile.in (target.o): Update dependencies.
Andreas.
