On m68000, all code is compiled softfloat, so functions
...
that return floats must do so in integer registers, as the
pre-SVR4 ABI code did. So in these functions we ignore
__SVR4_ABI__ if __HAVE_68881__ is not also set.

Use the EXTBL macro where we want the extbl instruction.
...
On the 68010 this expands to an extw/extl combination.

On the 68010 only, assemble a different version of

this function, since the 68010 doesn't have bit
instructions.

On the 68010, we are forced to do bytewise compares

and copies if the two addresses aren't of the same
evenness.

I have no idea why this syscall wrapper does some very un-unix-like
...
argument prefrobbing, in particular, it computes max(addr, __minbrk)
and uses that. The code is like this even in the ancient libc/i386 tree,
back to the earliest rev 1.2. I did not see it Lite 1, but I'm not totally
sure what the random site I found was serving up.

* However, I do know that it should use jb and not jl.

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.
