[Bug ld/22846] i686-w64-mingw32 cross linker generates truncated binary image

[despair at rvx86 dot net]

It also silently fails when linking executable images:

/* test.c */
#include 

main(argc, argv)
char **argv;
{
puts("hi bugzilla");
return 0;
}

compile with:
i686-w64-mingw32-gcc test.c -o test.exe
or
i686-w64-mingw32-clang test.c -o test.exe

(Since Clang is also the system compiler on my platform, I manually renamed the
Clang cross-compiler after building it.)

This:

_gcov_indirect_call_profiler_v2.o has

  1a:   8d 04 1d 00 00 00 00lea0x0(,%ebx,1),%eax
  21:   e8 fc ff ff ff  call   22
<__gcov_indirect_call_profiler_v2+0x22>

with the R_386_TLS_GD reloc above; the executable has

 805224a:   65 a1 00 00 00 00   mov%gs:0x0,%eax
 8052250:   05 fc ff ff ff  add$0xfffc,%eax
 8052255:   90  nop

without any relocs.

Btw., please note that I'll be on an extended vacation starting
tomorrow, with little or no net access for a month.

PR ld/22832 on SPARC.

The fix for PR ld/22727 on SPARC passed TRUE as the 'create' argument
in the call to bfd_link_hash_lookup.  It turns out this was a bad idea
because, if the symbol is created at this point, the link will abort
later in elf_link_output_extsym.  This changes the TRUE into a FALSE
and puts an assertion on the result of the call, making it easier to
debug the issue; that's exactly in keeping with what Gold does.

bfd/
* elfxx-sparc.c (_bfd_sparc_elf_check_relocs) :
Pass FALSE instead of TRUE as 'create' argument to bfd_link_hash_lookup
and assert that the result of the call is not NULL.

Can't we use a variable EMULATION or some such?

Can't we have specific *.?d files for Solaris?
