1376 # Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
1377 # But there are times where we need a bit more control. The motivating
1378 # and currently only case is Android: this is almost identical to
1379 # {x86,arm,mips}-linux, but not quite. So this introduces the concept of
1380 # platform variant tags, which get passed in the compile as
1381 # -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
1382 #
1383 # In almost all cases, the <variant> bit is "vanilla". But for Android
1384 # it is "android" instead.
1385 #
1386 # Consequently (eg), plain arm-linux would build with
1387 #
1388 # -DVGP_arm_linux -DVGPV_arm_linux_vanilla
1389 #
1390 # whilst an Android build would have
1391 #
1392 # -DVGP_arm_linux -DVGPV_arm_linux_android
