Just stepping back a bit, some linkers are more tolerant than others 
about the order of flags and such.  Libraries that land in standard 
locations like /usr/lib also obscure this issue, by rendering irrelevant 
an improperly-placed or -constructed -L flag.

Because of this, you will find a fair number of bad Makefile.am examples 
out in the wild.  You don't find out that you've been emulating one of 
these bad examples until you try your package on a system with a 
stricter linker or one that places libraries you need in odd places.
