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.

This should be already handled by the code on lines #176 and #439:
http://crosstool-ng.org/hg/crosstool-ng/file/7a5ee8d36a1d/scripts/build/cc/gcc.sh#l176
176 for tmp in ARCH ABI CPU TUNE FPU FLOAT; do
177 eval tmp="\${CT_ARCH_WITH_${tmp}}"
178 if [ -n "${tmp}" ]; then
179 extra_config+=("${tmp}")
180 fi
181 done
(same code on line #439 for the final gcc)
Isn't it the case for you?
Regards,
Yann E. MORIN.
