 build system: Persist CrossCompiling in binary distributions

 The build system uses the CrossCompiling variable to decide whether or
 not we should build various packages that must be built using the
 compiler.  Consequently, it is important that we persist its value in
 the binary distribution so we know during `make install` not to go
 looking for files that would have been built for these packages. Failing
 to do this causes #13325.

 Test Plan: Cross compile, `make binary-dist`, and try installing the
 binary distribution on the target
