1397 # Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
1398 # But there are times where we need a bit more control. The motivating
1399 # and currently only case is Android: this is almost identical to
1400 # {x86,arm,mips}-linux, but not quite. So this introduces the concept of
1401 # platform variant tags, which get passed in the compile as
1402 # -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
1403 #
1404 # In almost all cases, the <variant> bit is "vanilla". But for Android
1405 # it is "android" instead.
1406 #

1408 #
1409 # -DVGP_arm_linux -DVGPV_arm_linux_vanilla
1410 #
1411 # whilst an Android build would have
1412 #
1413 # -DVGP_arm_linux -DVGPV_arm_linux_android
