Subject: [PATCH] cmake: Use find_program if find_host_program is not
 available

CMake does not define the `find_host_program` command we've been using
in the cross-compiling code path.  It was provided by a widely used
Android toolchain file.  For compatibility, continue to use
`find_host_program` if available, but otherwise use just `find_program`.

Upstream-Status: Accepted
[https://gitlab.kitware.com/cmake/cmake/merge_requests/1009]
        - Will be in 3.10
