[Intel-gfx] [PATCH] intel-gpu-tools: fix version.h creation in android

[tim.gore at intel.com]

From: Tim Gore <tim.gore at intel.com>

commit 743dc7997aa9f5210055896940d87c88983dcda6
breaks the build under Android because version.h
is not created. This happens because the android
make executes from the ANDROID_BUILD_TOP directory
rather than from the directory containing the source
files, so we need Android specific make instructions
to generate version.h
