   1 # SUBARCH tells the usermode build what the underlying arch is.  That is set
   2 # first, and if a usermode build is happening, the "ARCH=um" on the command
   3 # line overrides the setting of ARCH below.  If a native build is happening,
   4 # then ARCH is assigned, getting whatever value it gets normally, and
   5 # SUBARCH is subsequently ignored.
