1375 # Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
1376 # But there are times where we need a bit more control. The motivating
1377 # and currently only case is Android: this is almost identical to
1378 # {x86,arm,mips}-linux, but not quite. So this introduces the concept of
1379 # platform variant tags, which get passed in the compile as
1380 # -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
1381 #
1382 # In almost all cases, the <variant> bit is "vanilla". But for Android
1383 # it is "android" instead.
1384 #
1385 # Consequently (eg), plain arm-linux would build with
1386 #
1387 # -DVGP_arm_linux -DVGPV_arm_linux_vanilla
1388 #
1389 # whilst an Android build would have
1390 #
1391 # -DVGP_arm_linux -DVGPV_arm_linux_android

5033 # build as 32-bit (IN THIS EXAMPLE).
