    testsuite/arm: Improve unsigned-float.c
    
    The test requires an FPU, so use -march=armv7-a+fp -mfpu=auto instead
    of -march=armv7-a.
    
    We also remove dg-require-effective-target arm_fp_ok, but keep
    dg-add-options arm_fp: this enables the test to pass on arm-eabi
    configured with default cpu/fpu/mode.
    
    dg-require-effective-target arm_fp_ok fails on such a configuration
    for lack of FPU, since dg-options are not taken into account by
    dg-require-effective-target.
    
    Add -march=armv7-a+fp -mfpu=auto is sufficient for arm_fp options to
    be acceptable.
    
    This enables the test to pass on all the arm-eabi configurations I'm
    testing, as well as arm-linux-gnueabi when forcing -march=armv5t.

            dg-options.
