Yes it does.

binutils-2.12.90.0.1/gas/config/tc-mips.c has a following part.
if (mips_arch == CPU_UNKNOWN && mips_cpu != CPU_UNKNOWN)
{
ci = mips_cpu_info_from_cpu (mips_cpu);
assert (ci != NULL);
mips_arch = ci->cpu;
as_warn (_("The -mcpu option is deprecated. Please use -march and "
"-mtune instead."));
}
When I set up following GCCFLAGS,
GCCFLAGS += -mcpu=vr4100 -Wa,--trap
the mips_arch is CPU_UNKNOWN and the mips_cpu is CPU_VR4100.
The gas print out warnning.
