The version of libtool you are running doesn't understand cross compilation
(sysroot) paths.  (Sysroot paths start w/ the '='.)  You should use "libtoolize"
prior to running to update the libtool configuration to match the changes that
OE/YP have.  This works in almost all cases.. (where it doesn't work usually
means someone had manually hacked on the previous libtool file...)
