chs 0c6e4dbbc4 ok, the change from rev 1.33 was unnecessary after all, 
only the second part of the previous revision was needed.
put the logic for the initial icache invalidation of the PLT
back the way it was, but in a way that makes clearer what's going on,
and add some comments explaining it.

chs 96fb424f44 fix two problems with icache invalidation of the PLT: 
- restore revision 1.33, it was correct.
 - fix pointer arithmetic in other calls to __syncicache().

skrll 38fb01be3a Apply fixes from Charles: 
- Fix how _rtld_relocate_nonplt_self deals with REL32 relocations.

- Change the assert so that it is correct for binutils 2.14 and 2.15.

There are still problems with the libraries generated with binutils 2.15,
but at least ld.elf_so doesn't crash.

thorpej 2a63e04007 - Change the strong dlfcn names in libc to ___name, and make the __name 
versions used by others in libc weak, so that we have:
	name: weak
	__name: weak
	___name: strong
- Add __name strong aliases of the dlfcn names in ld.elf_so, so that we have:
	name: strong
	__name: strong

This allows ld.elf_so to self-resolve both the name and __name variants
of the dlfcn functions, the former being required for dlfcn support in
applications, the latter being required for dlfcn support in libc.

Fixes the problem described in:

cube d1b3d841ee Make ld.elf_so use the new sysctl API. That allows the user to give any 
sysctl variable name in /etc/ld.so.conf.  It also makes the ld.elf_so
binary slightly smaller (at least on i386), and has no impact on
performance.

skrll 701ae47cdf Fix the dynamic linker for hppa using ELF. 
Lazy binding doesn't work 100% of the time so force immediate binding.
One possible reason is that the PLT stub blows away r20 which the
compiler might not take into account.
