build: run AC_CANONICAL_HOST only

There is no need to call AC_CANONICAL_SYSTEM when only
AC_CANONICAL_HOST is needed. Also, checking for $target is factually
incorrect, since we do not produce object code like a compiler. Use
$host, which specifies the triple/quadrople where the compiled program
is supposed to run.
