thread specific informations.
In order to do that, and in order to avoid KBI breakage with existing
infrastructure the following semantic is implemented:
- For live programs, a new member to the PT_LWPINFO is added (pl_tdname)
- For cores, a new ELF note is added (NT_THRMISC) that can be used for
storing thread specific, miscellaneous, informations. Right now it is
just popluated with a thread name.
GDB, then, retrieves the correct informations from the corefile via the
BFD interface, as it groks the ELF notes and create appropriate
pseudo-sections.

it exists in order to allow arch-specific overrides. This fixes the
binutils (and world) build on powerpc64 after recent TBEMD merges.

I've had a report of a sparc64 system where cc1 generates illegal
instructions. We still have to diagnose this properly, but instead of
hosing all sparc64 boxes out there, fall back to libgcc to prevent more
damage.

libcompiler_rt.a is a BSD licensed C language runtime, which implements
many routines which are linked into binaries on architectures where
certain functionality is missing (e.g. 64 bits mul/div on i386).
Unfortunately, libcompiler_rt cannot replace libgcc entirely. Certain
features, such as an unwinder for exception handling, are missing.
That's why only libgcc.a is replaced for now, because this one does seem
to be complete.
Tested by: rene (amd64), nwhitehorn (powerpc), droso (i386 exprun)
and many others. Thanks!

Once we use libcompiler_rt, the LIB-line must go, to prevent libgcc.a
from being built. Therefore, just hardcode the name.

TARGET_BIG_ENDIAN is now completely dead, except where it was
originally supposed to be used (internally in the toolchain building).
TARGET_ARCH has changed in three cases:
(1) Little endian mips has changed to mipsel.
(2) Big endian mips has changed to mipseb.
(3) Big endian arm has changed to armeb.
Some additional changes are needed to make 'make universe' work on arm
and mips after this change, so those are commented out for now.
UPDATING information will be forthcoming. Any remaining rough edges
will be hammered out in -current.
This is done by prepending the file to elfxx-ia64, not appending it.
Additionally, reduce diffs between Makefile.amd64 and Makefile.ia64;
instead of echo'ing defines in Makefiles, just add the needed define to
elf-fbsd-brand.c directly, as it is only used for amd64 and ia64.
tc-sparc-fixed.c entirely, since the fix has been integrated into
contrib/binutils/gas/config/tc-sparc.c by upstream. Define TARGET_OS
in addition to the other TARGET_XXX defines.
