1404 # Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
1405 # But there are times where we need a bit more control. The motivating
1406 # and currently only case is Android: this is almost identical to
1407 # {x86,arm,mips}-linux, but not quite. So this introduces the concept of
1408 # platform variant tags, which get passed in the compile as
1409 # -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
1410 #
1411 # In almost all cases, the <variant> bit is "vanilla". But for Android
1412 # it is "android" instead.
1413 #
1414 # Consequently (eg), plain arm-linux would build with
1415 #
1416 # -DVGP_arm_linux -DVGPV_arm_linux_vanilla
1417 #
1418 # whilst an Android build would have
1419 #
1420 # -DVGP_arm_linux -DVGPV_arm_linux_android
1421 #
