ed472989a6 Implement a significantly improved version of memccpy(), with thanks to 
Ignatios Souvatzis for correcting the SVR4 ABI code and for a few
micro-optimizations that followed from these changes.

The overall improvement was measured at 3-4x for copies of at least
4 bytes on the 68030, and 8 bytes on the 68040.  For smaller copies
the improvement was still measurable, if not as dramatic.

5aefcfdc06 Create shared ARM source for libc, and move arm26 port over to using it. 
The code is (almost) a direct copy of the current arm26 sources.
It's identical to the current arm32 sources, with the following exceptions:
 - _C_LABEL is used on references to C labels from assembler.
 - Function returns in assembler have APCS-26 versions in #ifdef __APCS_26__.
 - It uses SoftFloat 2a rather than SoftFloat 1a.

The first two of these should be inconsequential.  I believe that SoftFloat 2a
should work on arm32 and be backward-compatible with existing code, but this
is not obviously true.  For now, arm32 remains using its own bits of libc.

e740400671 Just use a store/load pair to get the pattern into the FP reg. This eliminates 
a bunch of cruft and avoids using a v9a instruction.
In addition, eliminate 8 of the fmovda's, which we are not using the result of
anyway.
Net result is that this should be faster in all cases.

of these system calls.

Note that __semctl13() doesn't require the extra stub that the old
semctl()/__semctl() did, as the SUSv2 version takes variable arguments,
and thus does not require the extra indirection.
