suggestion for adding sdk/lib to pluginapp.bin or libuno_sal.so symlink in ure/lib

Hi, I'm tinkering with lo 4.2.4.2 and am having a bit of an issue 
building pluginapp.bin in the extensions path, as it needs libuno_sal.so

The following is where all the flavours are found in the build tree:
> $ find . -name 'libuno_sal.so*' | xargs stat -c"%N"
> ‘./instdir/sdk/lib/libuno_sal.so’ -> ‘../../ure-link/lib/libuno_sal.so.3’
> ‘./instdir/ure/lib/libuno_sal.so.3’
> ‘./instdir/ure/lib/libuno_sal.so.3-gdb.py’
> ‘./workdir/Dep/LinkTarget/Library/libuno_sal.so.3.d’
> ‘./workdir/LinkTarget/Library/libuno_sal.so.3.objectlist’
> ‘./workdir/LinkTarget/Library/libuno_sal.so.3.exports’
> ‘./workdir/Headers/Library/libuno_sal.so.3’

This is the error encountered:

ld: fatal: library -luno_sal: not found
=================================

Either 'sdk/lib' needs to be added as a runpath-link (which works fine 
manually) or a symlink to libuno_sal.so.3 would need to be created in 
'ure/lib' as that path is already used.

Thanks in advance for suggestions on how one might successfully do this, 
it doesn't seem intuitive looking at the makefiles in
${src}/extensions/Executable_pluginapp.bin.mk and
${src}/sal/Library_sal.mk

FWIW, this is building with patches on pkgsrc under SunOS with gcc and 
solaris ld so don't be too worried about the noise in the above fragment.
