But this is not an assembler flag! quiet_cmd_vdso32as = VDSO32A $@ cmd_vdso32as = $(VDSOCC) $(a_flags) $(CC32FLAGS) $(AS32FLAGS) -c -o $@ $< where ifdef CROSS32_COMPILE VDSOCC := $(CROSS32_COMPILE)gcc else VDSOCC := $(CC) endif The name of the make variable AS32FLAGS is a bit misleading. This variable does not hold arguments to as, it holds arguments to the compiler driver, "gcc". Segher
