[oe] [PATCH 2/2] meson: set native tools

[Ross Burton]

When cross-compiling meson respects the usual CC, CFLAGS and so on environment
variables for *native* tools not *cross* tools, so instead of unexporting CC we
should re-export the right tools.

Not only is this the right thing to do, but recent changes to oe-core means that
the default compiler binary (cc) isn't in PATH, so Meson can't build native
binaries.
