Shared libraries reference dependencies with absolute paths

[arrrow-pk]

Not too sure of the scope of this problem but I am building on Mac OSX for QNX and I noticed that the generated shared object files referenced their dependencies with absolute paths. I.e. ntoarmv7-objdump on libboost_thread.so lists "bin.v2/libs/system/build/qcc/release/target-os-qnxnto/threading-multi/libboost_system.so.1.52.0" in the dependencies section irrespective of the hardcode-dll-path option. This caused problems when trying to deploy the lib to a device. On digging further it seems that HAVE_SONAME is missing from qcc.jam which is causing the -Wl flag to be excluded from the link command in the "actions link.dll bind LIBRARIES" section. Removing HAVE_SONAME solves the problem, i.e:

--- a/tools/build/v2/tools/qcc.jam
+++ b/tools/build/v2/tools/qcc.jam
@@ -232,5 +232,5 @@ rule link.dll ( targets * : sources * : properties * )

  }

Hopefully this helps someone else save some time :)
