This is kind of "multilib", where one machine can run binaries of multiple
architectures, like 32bit and 64bit, while uname tells about the underlying
POSIX-like system only (which provides the SHELL).

For example, I'm using x86_64 Cygwin to run cl.exe creating 32bit binaries,
which can be executed, so it's not a "cross"-compile. Now the host triplet
should be i686-pc-winnt, but uname can tell x86_64 (cygwin) only.
