libnosys/warning.h: fix asm line delimiter

[Hans-Peter Nilsson]

The ";" character is *not* a universal assembly line delimiter.
It is target-dependant, and has to be autoconfed in the general
case.  For CRIS and the hppa, it's a start-of-comment character.
I seem in gas that the same goes for more than a dozen targets.
I guess it's just luck that none of them use libnosys/warning.h.
Glibc has it target-configurable because it needs to emit single
assembly lines.  In this case however, it's alright to emit more
than one assembly line, so that's what I suggest.  (By default,
GCC uses "\n\t" to delimit its insn output, but FWIW I thought
the space is just as good to keep and slightly more readable.)

Without this patch, I see (cut-n-pasted) for cris-axis-elf:
