native.bbclass: use BUILD_* variables

Instead of replicating the logic for the host compiler naming from bitbake.conf,
use the BUILD_* variables directly.

Also change BUILD_CPP to use gcc -E (which native.bbclass previously used), as
some recipes (e.g. grub-efi) use ${CPP} with multiple input files, which gcc -E
can handle but cpp can't.
