meson: Allow building intel-clc for the host if it can be run

In what is probably the most common case  cross of compilation, x86_64
-> x86, it should be possible to build intel-clc for the host machine
and run it. Doing so simplifies the build by not needing to be able to
cross compile half of mesa, and should ease developer and distro strain
for building Intel drivers for x86.
