Do not use explicit -L for standard library directories
Do not use explicit -L for standard library directories

A functioning compiler has the correct standard library directories
(be that /usr/lib, /usr/lib32, /usr/lib64 or whatever else) in the
default set of directories it feeds the linker.  Passing these
explicitly is superfluous at best.  In the status quo, they are
being passed before other options added by SCons, so they cause the
linker to find libraries in /usr/lib64 before finding locally-built
ones, which can break the build or have worse unintended consequences.
