LD_CONFIG_PATH, LD_RUN PATH are not honored, unfortunately DLLs use the same 
search path as executables, so to use $(libdir) I would need to set:

export PATH="$PATH:$libdir"

I am not sure if -rpath works, I will check.

OK, I will wait for Cygwin to be fixed (fixing it by myself involves more 
knowledge that I have).
