493acb76cb More alloca() -> malloc(). Needed to make some shared libraries link when 
compiled with -g.

9b25bfd178 Semi-random code cleanup. 
Also, in the RRS_PARTIAL case, go ahead and allocate a relocation entry if the
bind failed.  (Who knows?  Maybe some day we'll allow relinking an executable.)

5a63d68e02 Fix two problems: 
* On other systems, `-Bsymbolic' does not affect undefined (external)
  symbols at all.  We were generating invalid PLT slots in this case.
* Do not prebind GOT and PLT slots when `-r' is used; only do so if
  -Bsymbolic is used {or if we're in RRS_PARTIAL mode, but I'm not
  sure that's correct}.  Otherwise, we could inadvertantly prebind
  symbols when using `-r' with PIC files; when the resulting .o file
  is then linked into a shared library, the library would not permit
  an executable to override its symbols as it's supposed to.

aca0169f10 open(2) can legally return 0. Errors only if return value < 0.

5551faab76 Don't abuse alloca() for allocating memory for string sections which can 
easily have a size of several megabytes exceeding the hard stack limit
of some ports. Patch supplied by Richard Earnshaw in PR bin/8547.

d1407362ba More and more .Os cleanups. .Os is defined in the tmac.doc-common file, 
so we shouldn't override it with versions in the manpages.  Many more to
come.

a5b9b9c815 Include sys/resource.h, because otherwise RLIMIT_STACK is not set 
and ld does not bump up its stack limit. This causes large links
(such as the kernel) to segfault on machines with a small stack
limit (particularly sparc, .5 MB).

ce394ac326 Add hook to convert some DISP32 relocs to BASREL through a GOT entry. 
[XXX not perfect since gotslot are allocated on a per-symbol basis but
not a per-symbol & addend tuple.  This makes impossible to have separate
GOT entries to ___sF (stdin), ___sF+88 (stdout), and ___sF+176 (stderr)]

a2030d670f Revert last change, since it treats external SIZE symbols as 
weak undefined symbols. The problem it tried to solve is
actually a bug in non bfd gas.new.

4f1a79cfbd Back out change to md_make_gotreloc which added 4 arguement of got_t *. 
Add argument to md_fix_jmpslot indicating whether this the first (i.e
tranfer) jmpslot or not.  Add better support for VAX (the VAX can support
pure text code; let ld that advantage of it).  Checking in verified and
working versions of rtld VAX support routines.
