Various packages use the paths to gcc libraries/includes etc. in various
places (e.g. libtool, *.la files, etc.). So any time you upgrade gcc
(say from 6.1.0 to 6.2.0 or 6.2.0 to 6.2.1), everything that has those paths
needs to be rebuilt. By having only the major number in the paths (which is
pretty much all that matters), you only have to rebuild when the major
version of gcc changes (at which time one usually want to mass rebuild
everything anyway).
