Not true.  TARGET_ARCH is automatically set.  You have to set
TARGET_ARCH/TARGET already if you are cross compiling, and
automatically set if not.

: This sounds as a hack, but couldn't you use file(1) on ${DESTDIR}/bin/ls
: to identify the architecture it's running ?  It would at least avoid
: breaking POLA.

Why is this a hack?
