Add more detail around how generation of configuration-independent files chooses a C compiler. Mention that setting HOSTCC or CC is recommended where there are multiple toolchains. Mention that the fallback location is the cc executable, which may help users troubleshooting when the file generation picks up the wrong toolchain (as in Mbed-TLS#10360).
