Make sure that we set CMAKE_NM, it's possible that some version of CMake could choose a host nm binary instead of the ones we just built. It's unlikely that host nm will understand our .dyn.relr segments unless it's from binutils 2.38 or higher, so it might complain.

# which doesn't work when using static linking.
|
|
# Instead, just tell CMake directly that the compiler works fine, so that it doesn't have to run
|
|
# a compile check before the build.
