* Makefile.def (build_modules): Add bison, byacc, flex, m4, texinfo. (flags_to_pass): Add FLEX. * Makefile.tpl (BUILD_DIR_PREFIX, BASE_EXPORTS): New. (BUILD_EXPORTS, HOST_EXPORTS, BASE_TARGET_EXPORTS): Include it. (DEFAULT_YACC, USUAL_YACC, DEFAULT_LEX, USUAL_LEX, DEFAULT_M4, DEFAULT_MAKEINFO): Remove. (CONFIGURED_YACC, CONFIGURED_FLEX, CONFIGURED_BISON, CONFIGURED_LEX, CONFIGURED_M4, CONFIGURED_MAKEINFO): Substitute. (YACC, FLEX, BISON, LEX, M4, MAKEINFO): Define to look into objdir or else use configured tool. (all-build): New. (all): Depend on it. (Build module dependencies): Add. * Makefile.in: Regenerate. * configure.in: Better support for multiple build modules, matching what is done for host/target modules. Do not look for "plausible" locations of build tools if Canadian cross. Use autoconf's AC_PROG_CC to find a C compiler. Define BUILD_DIR_PREFIX. Look for flex, makeinfo and m4. * configure: Regenerate.
