Fix explicit -sdk iphoneos builds

The order in which exclusive builds are added affects the order of
values in SUBTARGETS. xcodebuild.mk parses the value of SUBTARGETS in
the Makefile and selects the first entry, which would always be
release-iphonesimulator regardless of the build type. This obviously
caused -sdk iphoneos builds to fail.

This patch switches the order of in which exclusive builds are added so
that the entries which are not present in a particular build type are
always added last.
