Rainer Orth - Aug. 15, 2011, 5:10 p.m.
This patch, on top of the crtstuff one, moves LIB1ASMFUNCS and
LIB1ASMSRC.  LIBGCC1, CROSS_LIBGCC1, and LIBGCC1_TEST are all unused and
are removed.

There's not much to call out here:

* As in the last patch, I've consistently used .S for assembler sources.

* Unless there's something special, the files are called
  $cpu_type/lib1funcs.S, doing away with the previous variation.  One
  could even handle this in libgcc/configure.ac if desired, doing away
  with most uses of LIB1ASMSRC.

* I've noticed a single unused file: config/sparc/lb1spl.S.

Tested as described in the patch submission.

	Rainer
