rpaths not working?

[Mike Hearn]

Hi Alexandre,

On my system at least it seems DLLs need the rpaths too, from a clean
build of HQ git tree I get this when starting:

      8697:     file=/opt/wine/lib/wine/ntdll.dll.so [0];  needed by /opt/wine/bin/../lib/libwine.so.1 [0]
      8697:     file=/opt/wine/lib/wine/ntdll.dll.so [0];  generating link map
      8697:       dynamic: 0x7ffd52dc  base: 0x7ff63000   size: 0x0007cb58
      8697:         entry: 0x7ff6f000  phdr: 0x7ff63034  phnum:          5
      8697:
      8697:
      8697:     file=libwine_unicode.so.1 [0];  needed by /opt/wine/lib/wine/ntdll.dll.so [0]
      8697:
      8697:     file=/opt/wine/lib/wine/ntdll.dll.so [0];  destroying link map
wine: failed to initialize: libwine_unicode.so.1: cannot open shared object file: No such file or directory


And sure enough the .dll.so files don't have an $ORIGIN/../ runpath in them.
This seems like winebuild magic, at least, I didn't see any obvious places 
in the build system to add the flags. Any idea what's going wrong here?

thanks -mike
