[Buildroot] [git commit] gpu-viv-bin-mx6q: fix compiling issues with EGL_API_FB

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=c9ecdd2b96ece42468e1dbaa26dbeda152aabd90
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

To compile with Vivante header and use framebuffer, it is necessary to
pass option -DEGL_API_FB. This option is declared in pkg-config file of
Vivante library. But many packages (especialy qt5 components) does not
consider these flags.

So instead of patching every packages that use EGL, it is more
convenient to patch Vivante headers.

This commit add #define EGL_API_FB on top of eglvivante.h when
necessary.

[Thomas: fix syntax error.]
