Ensure libraries linked are listed after objects using them

The Ubuntu toolchain uses -Wl,--as-needed by default, which causes
libraries to be dropped from the final binary if they aren't used.  For
portability, make sure that libraries are always listed on the linker
commandline /after/ the objects that reference them.
.
This also avoids passing -l options to the compiler when compiling .o files.
