* automake.in (yacc_lex_finish_helper): Fix definition of YLWRAP

when ylwrap is installed in a default aux dir found in a parent
package.
* tests/subpkg.test: Augment to check that YLWRAP is installed
properly.
* doc/automake.texi (Yacc and Lex): ylwrap is not sought is the
current directory.
Report from Norman Gray.
