Those are generated by external C functions. But it seems the path is
wrong (Blocks/ should be ommited). I'll fix it quick (r15244). I now
also filter out paths that do not exist (Linux ld won't warn about paths
that don't exist). But it sort of makes everything look like magic when
suddenly some library gets the LibraryDirectory automatically added.
People will need to read the specification, I guess.
The magic comes from:
12.9.4 Annotations for External Libraries and Include Files
Now when I
$ mkdir -p ".../lib/omlibrary/Modelica\ 3.2.1/Resources/Library/linux64"
$ omc +s a.mo Modelica
$ make -f M.makefile
...
g++-4.4 ... "-L/home/martin/trunk/build/lib/omlibrary/Modelica
3.2.1/Resources/Library/linux64" ...
And if the library doesn't exit, the -L is not generated.

What's producing those references to a non-existent
Blocks/Resources/Library? I'm running with a checkout from the trunk,
built and installed today. No Blocks/Resources/Library.
