lukem f85d2d1c14 Use ${HOST_SH} instead of `sh'.
If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH;
Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

- Import new Motorola 060SP packages in /sys/arch/m68k/060SP first.
- if you had to change something in here, "make clean" here
- commit Makefile Readme.NetBSD makeas.sh makeoffs.awk
- "make" here
- commit this directory

Method:

Out of the table, we create a wrapper for fplsp.S. It contains:

Single precision:

	movl	sp@(4),sp@-			4
	bsr	_060fplsp+theoffset		4
	fmovs	fp0,sp@				4
	movel	sp@+,d0				4
	rts					2
	(18 bytes)

Double precision:

	movl	sp@(4+0),sp@-			4
	movl	sp@(8+4),sp@-			4
	bsr	_060fplsp+theoffset		4
	fmovd	fp0,sp@				4
	movel	sp@+,d0				4
	movel	sp@+,d1				4
	rts					2
	(26 bytes)

For __SVR4_ABI, the code is much shorter... it reduces to a single jbra.
