This has happened in the past. OK, but let users, who still build kernels as root, alone. In `19-rc3/include/Kbuild.include', just below `as-instr' i see: ,-- |cc-option = $(shell if $(CC) $(CFLAGS) $(1) -S -o /dev/null -xc /dev/null \ | > /dev/null 2>&1; then echo "$(1)"; else echo "$(2)"; fi ;) | |# cc-option-yn |# Usage: flag := $(call cc-option-yn, -march=winchip-c6) |cc-option-yn = $(shell if $(CC) $(CFLAGS) $(1) -S -o /dev/null -xc /dev/null \ | > /dev/null 2>&1; then echo "y"; else echo "n"; fi;) `-- so, change to `-o /dev/null' in `as-instr' will just follow this. ____ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
