  This comment was not very clear to me.  I guess you mean
# The configure script autodetects the host architecture, so we must
# pass the target architecture explicitly.

  When you use GENTARGETS, you must also specify the install commands.
However, you can probably keep using AUTOTARGETS.  Even when you use
AUTOTARGETS, it is possible to override the CONFIGURE_CMDS and BUILD_CMDS.
But you don't even need to override the BUILD_CMDS.  Instead, you can
pass additional options to the MAKE call, by defining

V86D_MAKE_OPT += CC="$(TARGET_CC) -D__i386__"

  (As Thomas mentioned, if you assign twice on the command line it is only
the last one that counts.)

  I can't guarantee that what I'm saying is correct, though, so be sure to
test with a clean build before resending.

  Regards,
  Arnout
