I investigated into --disable-static builds, and it looks like a libtool 
bug to me.

A testcase is attached for the libtool devs, and so this goes Cc there.

DESC: If -static is specified at the libtool command line, it ignores 
the fact that it may nevertheless has to link against a .la/.so file 
(e.g. due to ./configure --disable-static or AC_DISABLE_STATIC), and 
thus wrongly encodes an rpath into the binary that I believe it should 
not. What libtool should have done is to create the helper script as it 
would when -static was not specified.
