Some turn-on macro/variable are re-arranged, buffer pointer is extended to
support 32/64b combination of target/host.

+This patch fix GL application start failure on qemu 0.14.0.
+
+Some turn-on macro/variable are re-arranged, buffer pointer is extended to
+support 32/64b combination of target/host.
+
+This is not perfect fix, and we need consider other GL alternatives in future.
