Reinstate bypass for call-to-undefweak reloc overflow on SPARC

[Eric Botcazou]

Hi,

It was presumably ditched when DaveM merged the 32-bit and 64-bit code. :-)
We need it for g++.dg/warn/weak1.C, otherwise the linker complains:

weak1.o: In function `main':weak1.C:(.text+0x24): relocation truncated to fit: 
R_SPARC_WDISP30 against undefined symbol `foo()'

extern void foo (void) __attribute__ ((weak));

int
main ()
{
  if (&foo)
    foo ();

  return 0;
}

Tested on SPARC/Solaris 10 and SPARC64/Solaris 9.  GCC 4.1.0pre was also 
regtested.  Applied as semi-obvious. :-)

        * elfxx-sparc.c (_bfd_sparc_elf_relocate_section): Reinstate bypass
        for call-to-undefweak reloc overflow.
