Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Pass --enable-new-dtags to the linker invocation by default. If
desired, one can turn off the generation of post-ELF standard dtags by
overriding it with --disable-new-dtags after the default switch.

Immediate effect of the change is that -rpath path is now stored both
in DT_RPATH and DT_RUNPATH tags, which is the right way to provide
rpath for dynamic linker supporting DT_RUNPATH per specification.

Merge r236137 from x86:
Enable GNU hash generation for dynamic ELF binaries.

While at it, sync the order of options with x86 and pass along the verbose
flag.

Bring in a subset of gcc fixes that were back ported to
the GCC 4.1 branch and are available under GPLv2.

Now that TLS is supported for sparc64 by both binutils 2.17.50 committed
in r218822 and rtld(1) committed in r219533 turn on TLS support in GCC.

Allow the targeted CPU type to be set via -mcpu instead of
limiting to the hardcoded equivalent of -mcpu=ultrasparc.
