FWIW we have this patch:

http://git.yoctoproject.org/cgit.cgi/poky/tree/meta/recipes-devtools/libtool/libtool/trailingslash.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 :(

Cheers,

[patch follows below]

A command like /bin/sh ../../i586-poky-linux-libtool   --mode=install 
/usr/bin/install -c   gck-roots-store-standalone.la 
'/media/data1/builds/poky1/tmp/work/core2-poky-linux/gnome-keyring-2.26.1-r1/image/usr/lib/gnome-keyring/standalone/'
 fails (e.g. gnome-keyring or pulseaudio)

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