--- Comment #4 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
I too, months ago, had run into this problem -- via the nvptx 'as' failing on
'-o /dev/null'... (which I'll fix anyway).  After a quick look at
'gcc/m2/tools-src/makeSystem' I did presume that the compiler is invoked there
only for some side effects (remember, '-o /dev/null'), and thus fixing this
might be...

... as simple as this.  (Then, of course, interrupted by higher-priority
things, and I never got back to this.)

Therefore, for what it's worth, conceptual ACK to this proposed change (which
I've not yet tested, but will, eventually).
