The syntax of my proposed solution was wrong. My local tests were not performed
on a clean source which is why I did not notice the suggested syntax didn't
work.
The proper syntax is:
ifneq (,$(filter $(DEB_HOST_ARCH),powerpc))
export DEB_CXXFLAGS_MAINT_APPEND = -DEIGEN_DONT_VECTORIZE
endif
@Patrick: Could you update the debian/rules file please to use the above syntax?
Thanks,
Adrian
