My point was that even more generally use of various command definitions
appears to be allowed. For example, we have sometimes used such scripts
and/or "CC=gcc" style aliases for formal platform testing. Cross
compilations in particular generally aren't possible without such
command redefinitions; for those you're usually replacing multiple
native (to the build system) commands with those in the cross-compile

Use of command redefinitions to affect the behavior of the compiler (as
by adding compiler options) is rather more of a dark gray area.
