* elf64-sparc.c (sparc64_elf_relocate_section): Adjust addend of
dynamic relocs against section symbols for the output section vma.
However, with the addition of TLS support in the upstream rev. 1.104
this fix was essentially reverted. After factoring out the common parts
of elf32-sparc.c and elf64-sparc.c a comment was added to elfxx-sparc.c
in the upstream rev. 1.27 as part of unrelated changes, saying that the
fix from elf64-sparc.c rev. 1.61 indeed should be implemented, but given
that some unspecified OS has a broken ld.so expecting broken relocations
deliberately is omitted.
As the current behavior actually violates the SPARC ABI, FreeBSD never
had such a broken ld.so and this is actually causing problems with at
least kernel modules linked with binutils 2.17.50 committed in r218822
without the workaround committed in r219340 in place, re-implement the
above fix in a way so that is only applied if the output format is
ELFOSABI_FREEBSD. In the upstream version it probably would make sense
to invert this check and only skip adjusting the addend for the OS with
the broken ld.so, once it's determine which one that is.

BFD is an object file library. It permits applications to use the
same routines to process object files regardless of their format.
BFD is used by the GNU debugger, assembler, linker, and the binary
utilities.
The documentation on using BFD is scanty and may be occasionally
incorrect. Pointers to documentation problems, or an entirely
rewritten manual, would be appreciated.
There is some BFD internals documentation in doc/bfdint.texi which may
help programmers who want to modify BFD.
BFD is normally built as part of another package. See the build
instructions for that package, probably in a README file in the
appropriate directory.
BFD supports the following configure options:
--target=TARGET
The default target for which to build the library. TARGET is
a configuration target triplet, such as sparc-sun-solaris.
--enable-targets=TARGET,TARGET,TARGET...
Additional targets the library should support. To include
support for all known targets, use --enable-targets=all.
--enable-64-bit-bfd
Include support for 64 bit targets. This is automatically
turned on if you explicitly request a 64 bit target, but not
for --enable-targets=all. This requires a compiler with a 64
bit integer type, such as gcc.
--enable-shared
Build BFD as a shared library.
--with-mmap
Use mmap when accessing files. This is faster on some hosts,
but slower on others. It may not work on all hosts.
Report bugs with BFD to bug-binutils@gnu.org.
Patches are encouraged. When sending patches, always send the output
of diff -u or diff -c from the original file to the new file. Do not
send default diff output. Do not make the diff from the new file to
the original file. Remember that any patch must not break other
systems. Remember that BFD must support cross compilation from any
host to any target, so patches which use ``#ifdef HOST'' are not
acceptable. Please also read the ``Reporting Bugs'' section of the
gcc manual.
Bug reports without patches will be remembered, but they may never get
fixed until somebody volunteers to fix them.
