cmake: api-tests: Allow CROSS_COMPILE to set C compiler
Cmake currently falls back to the default C compiler on the system,
which may not be an appropriate embedded toolchain in every case.
This commit checks for a `CROSS_COMPILE` field that can be
passed in to indicate the specific GCC cross-compiler to use. If no
matching value is found, it defaults to the system C compiler,
as was the case previously.
