[PATCH]: Add DWARF debugging format support for arm-wince-pe

- Subject: [PATCH]: Add DWARF debugging format support for arm-wince-pe
Hi all,
The attached patches to bfd, gas and ld's testsuite,
add DWARF debugging format support to arm-wince-pe.
The work is based on the i386 coff ports.
It resolves (mostly) around:
- Moving dwarf related present code out of elf only blocks.
- Handling the dwarf related pseudos.
- Handling the .secrel32 pseudo, and consequently,
- Handling the section relative relocs.
Tested on arm-wince-pe and arm-none-eabi for binutils regressions,
and with arm-wince-gdb.
I don't know which is the correct value to return in
bfd_get_sign_extend_vma. I tested it with 1 and 0, but found no
difference.
What is the correct value? How does one test for it?
Cheers,
Pedro Alves
