over system libraries by fixing up the order libs are passed to gcc and the linker.
Ideally preference could be by-target instead of global, but our SCons implementation
is not currently utilizing different SCons build env()'s as we should.
Overally the current approach within these scripts is to prepend paths of preference
and append all others, but this does not give enough control (particularly due to the
approach of assuming /usr/LIBSCHEMA and letting paths be parsed and added by pkg-config).
In effect /usr/lib is likely to come before /usr/local/lib which makes linking against
custom built icu or boost impossible when those libraries are available in both places.
Sorting using a priority list allows this to be controlled, and fine tuned.
