Don't hard code the assembler name.
(MacOSX snapshots [at least] of SDCC call it sdas8051)
Fix deprecated name warnings. ie..
bit -> __bit
sfr -> __sfr
xdata -> __xdata
_asm -> __asm
_endasm -> __endasm
interrupt -> __interrupt
at -> __at
Make 'make' and 'make clean' work from the top of the tree.
SYNCDELAY() -> SYNCDELAY

This makes the define compatible with GPIF designer generated code.
Reset the toggle when clearing a stall. This is necessary otherwise a
stall will cause data toggles to (potentially) mismatch and data will
be lost.
Change default assembler to sdas8051 as that is what it is on all
systems I used.
Cast to WORD (not sure it's necessary) and put braces around the arguments.
