I just tested this, and make.conf overrides iuse defaults.  To verify
this for yourself, pick a package with an iuse default turning on a
flag, then turn off the flag in make.conf and check what would happen if
you emerged the package.

package.use overrides for a single package, but make.conf overrides for
all of your system.
