854e6cd69f Add TLS support for AMD64, i386 and SH3. 
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

12bd4dbd45 PR/39240: Satoshi Suetake: Don't fail when attempting to resolve weak symbols 
when we are doing immediate binding, leave them alone and they will be dealt
with later during lazy binding. From skrll@

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.

3ed9ffcae1 Explicitly prefix ld(1) options in LDFLAGS with "-Wl," rather than 
using the ${LDFLAGS:@F@-Wl,$F@} make substitution because that breaks
if LDFLAGS is already set.

255de8f40e Preserve r2 in _rtld_bind_start - in r2 functions that return 
aggregate types are passed the address of the memory area to store the
returned result to.

6f0fac5efa Pass down an additional flag to _rtld_relocate_nonplt_objects() which 
indicates whether we're relocating ld.elf_so itself.  Use this in some places
rather than hackish tests on `dodebug'.  (The Alpha and HPPA `dodebug' tests
were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore
dodebug is always true.)

0df8d18100 Introduce a new flag, `isdynamic', which is used to remember whether the 
executable was of type ET_DYN.  Use this instead of `mainprog' to determine
whether we need to do base-relative fixups of the PLT.  (This allows loading
non-relocatable objects, should we desire to do that at some point...)

a04012e731 Split _rtld_relocate_plt_object() into two MD functions: 
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT.  (On
  most platforms it just does a simple base-relative fixup; on SPARC it does
  nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms.  A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

NOT tested on: hppa sh x86_64

bdc2ac1520 A few things: 
* Pass a symbol number to _rtld_find_symdef(), not a r_info.
* Don't try to do a symbol lookup when we find an unsupported relocation;
  instead get the symbol name from the referencing object's strtab.
* Add preliminary support for `-z combreloc'-style startup optimization on
  i386, `#ifdef COMBRELOC'.

74444a2ddb Rename _rtld_relocate_nonplt_object() to _rtld_relocate_nonplt_objects(), 
and push the outer loop into it.  This actually shaves a couple % off startup
time at least on PCs.
