FWIW we have this patch:

which seems to help. We've never been able to clean it up enough to
submit upstream or have a reliable test case for it though :(



[patch follows below]

A command like /bin/sh ../../i586-poky-linux-libtool   --mode=install 
/usr/bin/install -c 
 fails (e.g. gnome-keyring or pulseaudio)

This is because libdir has a trailing slash which breaks the comparison.
