FYI: fix DT_RUNPATH detection code again

[Ralf Wildenhues]

Sigh, I don't know what I was thinking when I wrote this.
Trying the Sun CC compiler (where $wl contains two words)
made the glitch obvious, by outputting an ugly error during
configure.

Applied to HEAD, does not exist in branch-1-5.

Cheers,
Ralf
