Patrick Georgi e4d660b2dc 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).
