Hi Raghav,

since you have been using meson build system a lot, could you add support for
cross-compilation to guix/build-system/meson.scm please?  I would do it myself
if I knew how.

See https://issues.guix.gnu.org/44244

See also https://mesonbuild.com/Cross-compilation.html

As it is now, a lot of basic guix packages will break when cross-compiling
since they have been switched to meson-build-system.
