The aarch64 toolchain is built without --with-cpu, so the CPU_CFLAGS_<type> entry in target.mk is the only place a -mcpu option comes from. The cortex-a72 (bcm27xx/bcm2711, mvebu/cortexa72) and cortex-a76 (bcm27xx/bcm2712) CPU types have no entry, so userspace for these subtargets is built with plain "-Os -pipe", which produces generic armv8-a code. The "doesn't correspond to a known type" warning is not visible because the target scan discards stderr. Add the missing entries. For cortex-a76 this also enables the ARMv8.2 features such as LSE atomics, which replace the out of line atomic helper calls.
