1446 # Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.

1448 # and currently only case is Android: this is almost identical to
1449 # {x86,arm,mips}-linux, but not quite. So this introduces the concept of
1450 # platform variant tags, which get passed in the compile as
1451 # -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
1452 #

1454 # it is "android" instead.

1457 #
1458 # -DVGP_arm_linux -DVGPV_arm_linux_vanilla

1460 # whilst an Android build would have
1461 #
1462 # -DVGP_arm_linux -DVGPV_arm_linux_android
