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.
Upstream-Status: Inappropriate [other] - depends on qemu gl patch
