The hard float abi and hard float are different, Hard float abi: Use float register to pass float type arguments. Hard float: Enable the hard float ISA feature. So the with_fp_cond cannot represent these two features. When -mfloat-abi=softfp, the float abi is soft and hard float is enabled. So add 'with_hard_float_abi' in preconfigure and define 'CSKY_HARD_FLOAT_ABI' if float abi is hard, and use 'CSKY_HARD_FLOAT_ABI' to determine dynamic linker because it is what determines compatibility. And with_fp_cond is still needed to tell glibc whether to enable hard floating feature. In addition, use AC_TRY_COMMAND to test gcc to ensure compatibility between different versions of gcc. The original way has a problem that __CSKY_HARD_FLOAT_FPU_SF__ means the target only has single hard float-points ISA, so it's not defined in CPUs like ck810f.
