Fixed compilation removing DOLT (from http://dolt.freedesktop.org/)
fom configure.in, else it would file like this(output stripped) :
.../doltlibtool: exec: .../libtool: cannot execute: No such file or directory
note that it looks for libtool and not ${TARGET_ARCH}-angstrom-linux-libtool
in my case,more informations are disponible reading the m4 dolt file here:
