As of 1.6.0, `meson env2mfile --debarch i386 --cross -o cross.txt` outputs
a cross-file that includes cmake = ['/usr/bin/cmake'].
Similarly,
`MESON_USE_NEW_CROSSGEN=1 /usr/share/meson/debcrossgen --arch i386 -o cross.txt`
outputs a suitable cross-file.
This is *not* fixed for the default code path, used when the environment
variable MESON_USE_NEW_CROSSGEN is unset.
So to solve this, either the debcrossgen in Meson's Debian packaging
needs to use what is currently the MESON_USE_NEW_CROSSGEN=1 code path
by default (possibly with an opt-out to go back to the old behaviour if
we are concerned about regressions), or consumers of information from
debcrossgen (which I believe means debhelper and debputy but nothing else)
need to be updated to invoke `meson env2mfile` instead.
