I've only refactored the code, it is originally Tor's I think; but
either way, I guess the reason is the comment following the check:

 # Prefer native x64 compiler to cross-compiler, in case we are running
 # the build on a 64-bit OS.

Ie. the check is unrelated to the ATL itself, but to the fact if we are
building native x64 Windows build (only base work done there IIRC, ie.
don't expect it to build), or x86 build, where we need to cross-compile
the x64 component.

Does it answer your question?  Or did I actually misunderstood yours?
