toolchain/toolchain-common.in: add BR2_TOOLCHAIN_HAS_LIBQUADMATH hidden symbol
This hidden symbol allow to know when libquadmath can be built and
installed.
Also, declaring this symbol in toolchain-common.in allows to use it in
both external and buildroot toolchain backend.
This will be needed for adding/improving the fortran support.
