Yes, I believe it will (Is this code ever invoked when *not* cross-compiling?).

However, I still think the CROSS_TOOLCHAIN_FLAGS should come last, as
this gives the user the opportunity to override any of our arguments
for any reason he sees fit. E.g., I can see how someone might want to
use CMAKE_BUILD_TYPE=Release for the host tblgen targets, but still
build the main thing in debug mode.

Is there any reason that can't be done?
