Fix build-many-glibcs.py arm-linux-gnueabihf builds with mainline GCC.
My fix to make the arm-linux-gnueabihf build-many-glibcs.py builds actually use the hard-float ABI as intended showed up another issue when building with mainline GCC: GCC now determines an FPU based on the selected CPU or architecture and gives an error for -mfloat-abi=hard when the CPU does not imply a choice of FPU. This patch fixes all the affected configurations to specify a suitable --with-cpu, --with-fpu or -mfpu option explicitly to avoid that error from GCC. Tested the relevant configurations with build-many-glibcs.py with mainline GCC. * scripts/build-many-glibcs.py (Context.add_all_configs): Specify CPU or FPU for ARM hard-float configurations.
