fix build break when using prebuilt toolchain

When doing a build with the prebuilt 4.4 toolchain a duplicate
symbol error is hit. This is due to the fact this symbol is
really defined system/core/include/system/window.h

opengl: Enable -flto and -ffast-math

OpenGL can be built with -ffast-math and -flto without
regressions. Enable them for an extra speed boost.

opengl: Work around linaro-gcc bug 879725

linaro-gcc 4.6-2011.10 ICEs when building matrix.cpp with
-fmodulo-sched when tuning for cortex-a8 (cortex-a9 is ok).
Until the compiler is fixed, disable -fmodulo-sched if we're
targeting cortex-a8 based devices, such as iMX53.

ensure compiler supports -flto

Change Iec2950b1d8fef30ef5530551b094e97c7ee91fa7 enabled
-flto in all builds. However, not all compilers support this
option. This changes ensures the flag is only used when its
supported

GLES2_dbg/test: Build with -fno-strict-aliasing

more aliasing violations will be added, and performance of tests
isn't overly important
