Standardize looking for tool chain alternatives
Add find_tool()
to CMake, which allows us to look for tool chain
variants of programs in a standardized way when doing cross-compliation.
The order in which tools are found before base variants is similar to
autoconf's AC_CHECK_TOOLS()
.
Note that the first commit in this merge request will reintroduce the issue that was fixed in c7bd2d0d, but hopefully we can find a more robust way of fixing that.
