Surely the ubuntu cuda maintainers patched 'include/host_config.h'
This is from the 7.5 nvidia packages:

=====================================
#if defined(__GNUC__)

#if __GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ > 9)

#error -- unsupported GNU version! gcc versions later than 4.9 are not 
supported!
=====================================

IMHO there may be a good reason for nvidia to do it (Please correct me 
if I'm wrong) :
