[PATCH] add m68k-uclinux-* target

[PATCH] add m68k-uclinux-* target

[Bernardo Innocenti]

Hello,

these binutils/GDB patches add the required bits to enable
the m68k-*-uclinux-* target.

For years, the uClinux toolchain has been based on m68k-elf
with rogue patches.  In 3.4, uClinux support has been merged
into GDB and binutils and the target triplet changed to
m68k-unknown-uclinux-uclibc.

So far, the only toolchain component that needs to handle
uClinux differently from m68k-elf is GCC, so these bits
are not strictly required except for consistency. These
additions are definitely required (but not sufficient)
to build the toolchain in a combined tree.

I have no CVS write access to the src repository, so
please commit these patches for me  (the diffs don't
include the regenerated configure scripts).

Oops!  I've just noticed I forgot the star after "m68*-*-uclinux*".
The correct patch to apply in bfd/ is:

Approved and applied (with the fix to config.bfd)

Applied something similar:
  - The list is alphabetically sorted
  - configure does not need to be regenerated.
