compiler-rt: Rename the rt libraries if compiled with arm hardfloat ABI

OE does not rely on tuple to deduce hardfloat ABI, but clang/llvm does
arm-yoe-linux-gnueabi is used for both soft and softfp and hardfp float
ABIs in OE, LLVM expects arm-yoe-linux-gnueabihf for it to be treated as
hardfloat ABI, and look for correct name for rt libraries.

We know when we compile them with Hard-float ABI so rename them in such
case so clang can find it when using -rtlib=compiler-rt it needs to
has 'armhf' suffix
