Fix bug found by Izumi Tsutsui -- if _rtld_find_symdef returned NULL, the
...
runtime linker would crash. Restore behavior similar to version 1.3, where
the runtime linker continues on, ignoring the symbol.

Fix how underfined weak symbols are treated -- before, ld.so would do nothing
...
with them, rather than defaulting them to zero. This caused breakage with
the drawf EH stuff and init/fini code when they weren't used by the caller
(and hence the appropriate handlers were left undefined). Also fix an un-
initialized variable in symbol.c that only MIPS MD code tripped over.

In the `I can't believe it's been broken all this time' department:
...
_rtld_bind_start must save and restore the condition codes. Varargs functions
(like, say, printf()) depend on the state of cr1 to determine whether they need
to store floating point registers in the save area. Without this, the first
call to any particular varargs function will fail if floating point values were
passed.

Reorganize PowerPC cold a little. The return value from _rtld_bind_pltgot()

was ambiguous in the case of a weak symbol that was not defined. This caused
RTLD_NOW to fail badly with shared libraries linked against the new crtbegin.o.
