ppc64_linux_convert_from_func_ptr_addr broken

[Andreas Schwab]

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.
