Patch from Isaac Dunham to work around the deficiencies in musl's regex engine (which break building under alpine linux).

Musl's regex engine doesn't support \| which changes the behavior of busybox
sed, breaks toybox grep... I need to come up with a musl patch, in the meantime
here's a workaround.
