Bug#677656: Acknowledgement (qt4-x11: FTBFS when armel is declared as foreign arch)

[Yann Dirson <ydirson@free.fr>]

To be complete, there is obviously another part of debian/rules that
causes problems (which I had missed at first because I had commented
out opengl flags completely): in the same way, "-opengl es2" is passed
to configure.

ifeq ($(vendor),Ubuntu)
gles2_architectures := armel armhf
else
gles2_architectures := none_for_now
endif
ifeq ($(DEB_HOST_ARCH),$(findstring $(DEB_HOST_ARCH), $(gles2_architectures)))
	extra_configure_opts += -opengl es2
else
	extra_configure_opts += -opengl desktop \
	                        -no-egl
endif
