Took me a while to find out that the problem is not in libtool at all.
Problem is that link in usr/lib/ is broken. Problem is triggered in
Makefile.am install-exec-hook.


Here comes the exact sed line:

GNU sed:
 nclab01:~$ echo /usr/lib | sed 's,\(^/\|\)[^/][^/]*,..,g'
../..

Busybox sed:nclab01:~$ echo /usr/lib | busybox sed
's,\(^/\|\)[^/][^/]*,..,g'
....
