[Buildroot] [toolchain-builder ] configs/common: enable Fortran support

[Romain Naour]

Fortran depends on wchar only for architectures requiring libquadmath.

Since uclibc toolchain built by toolchain-builder enable locales (so wchar
is automatically selected), it's safe to enable unconditionally Fortran
support for all toolchains.
