commit 8e52f573a1e0c2c39968051bcf683805540deb03

    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.
