# Terribly terrible hacks: since our base Debian image ships with GCC 5.0 which breaks older kernels,
# revert the default to gcc-4.9. Also, since some customers use some very old distributions whose kernel
# makefile is hardcoded for gcc-4.6 or so (e.g. Debian Wheezy), we pretend to have gcc 4.6/4.7 by symlinking
# it to 4.9
