3998	OMC does not search in the correct places for libs under Linux	Dietmar Winkler	Martin Sjölund	"When working on [https://github.com/modelica/Modelica_DeviceDrivers/issues/114 Modelica_DeviceDrivers gh#114] I tried to run (on OpenModelica 1.11.0~dev-42-g1a73b84 under Ubuntu 16.04 64bit):

{{{#!mo
model Try4
  parameter String mem_name = ""COM4"";
  import Modelica_DeviceDrivers.Communication.SharedMemory;
  import Modelica_DeviceDrivers.Communication.SharedMemory_;
  import Modelica_DeviceDrivers.Packaging.SerialPackager;
  import Modelica_DeviceDrivers.Packaging.SerialPackager_;
protected
  SharedMemory sm = SharedMemory(mem_name, 16 * 1024);
  SerialPackager pkg = SerialPackager();
equation
  SharedMemory_.read(sm, pkg);
  annotation(uses(Modelica_DeviceDrivers(version=""1.4.4"")));
end Try4;
}}}

which compiles fine and even seems to execute but I got a translation warning:

{{{
[4] 09:08:37 Translation Warning
[Modelica_DeviceDrivers.Communication.SharedMemory: 17:3-25:17]: 
Could not find library pthread in either of:
  /usr/lib/x86_64-linux-gnu/omc/libpthread.a
  /usr/lib/x86_64-linux-gnu/omc/libpthread.so
  /usr/lib//libpthread.a
  /usr/lib//libpthread.so
 ...
}}}

the lib actually resides in:
{{{
$ locate libpthread.a
/usr/lib/x86_64-linux-gnu/libpthread.a
/usr/lib32/libpthread.a
/usr/libx32/libpthread.a
}}}

Same goes for `librt`.

So OMC should first search `/usr/lib/x86_64-linux-gnu/` then `/usr/lib/x86_64-linux-gnu/omc/`
