cc/gcc: pass --with-float to configure

The --with-float configure option defines the default -mhard-float, -msoft-float
or -mfloat-abi option of the built GCC. The --with-float option is ignored if
any of the latter options is passed to GCC.

Currently, these options are passed to GCC through the C(XX)FLAGS_FOR_TARGET
environment variables, but these variables are only used to build GCC's internal
stuff and libraries. Hence, --with-float has to be passed to GCC's configure to
define the default options of the final GCC.
