[Dev] [PATCH] src/lib/librelib: separate LIBRETOOLS_LIBDIR by ':' and consider each part as a candidate for searching the requested script

[Andreas Grapentin]

Hi,

I would like to enable librelib to support multiple locations in
LIBRETOOLS_LIBDIR. A patch to add that functionality is attached.

comments?

Thanks,
