If you should really get problems with this, you can manually
remove the corresponding *5.1* line(s) from
/etc/ld.so.conf.d/05gcc-x86_64-pc-linux-gnu.conf
or change the order and then call env-update.
Note that calling gcc-config afterwards would recreate your
original file again, so you do not really have to safe it.

However, so far I had no problems. OTOH, I do not use a heavy
C++ desktop and had already recompiled practically everything with 4.9
