The upstream code already does that (host_m32 is for the host components, and
target_m32 for the bootloader itself).  It's clear we need target_m32, but for
host_m32 we don't know what works and what doesn't, so we can only stick to
what upstream decided for us.

Our problem, however, is not really to decide wether to use 32 or 64 bit for the
host part, but to add biarch build-dependencies in case 32-bit is going to be

To summarise:

  - To change host_m32 variable please check if that works and get in touch with
    upstream (grub-devel@gnu.org).

  - In case host_m32 is going to be set, we (debian) need to add the appropiate
    biarch build-dependencies, but we still need someone to confirm these work
    at least to get the thing building.
