[Buildroot] [PATCH 1/6] core: export a variable with the host's bitness

[Yann E. MORIN]

Some host packages (e.g. host-pseudo) wants to know the host bitness,
and they can fail to detect it in some corner cases (as reported by a
few users on IRC).

Export a variable with the bitness of the host, so that those packages
can be made to behave.
