crossgcc: Enable rv32iafc-ilp32 configuration
rv32iafc-ilp32 is compatible with rv32iac-ilp32 for library implementation, so add a reuse rule allowing the default configuration to support rv32iafc. -IAFC is an unusual configuration (much less common than -IMAFC), but multilib reuse has essentially no cost: this change is useful to users of platforms that support hardware floating-point but cannot use hardware multiply/divide for any reason. To avoid generating a new set of libraries this is limited to the soft-float ABI. Tested by verifying that `gcc -march=rv32iafc -mabi=ilp32 --print-search-dirs` refers to the rv32iac/ilp32 library directory as expected, rather than just the root library directory as occurs when an unsupported target is selected (for instance, rv32id).
