Why is this needed here, it seems to be called before each individual
config anyway.

These variables bar PATH are unused by meson build, so should be removed
here to avoid giving the impression they are use. $CROSS is used by the
script so perhaps it can be kept. However, the whole point of the
cross-files is that you include all the needed details of your compiler
there. I think we should move away from using the CROSS value completely,
and use the cross-files properly.

I don't think we should force the builds to be always put into the base
directory. Instead of using cd, I think we should instead capture the base
directory path and pass that to meson.

Why does this need to be done each time?
