    Merge branch 'master' into testsuite-work
    
    Commits merged from master:
     - tests: various minor tweakings, mostly related to AM_PROG_AR
     - maint-mode: fix botched configure messages
     - fix: regenerate Makefiles
     - tests: few improvements to some `ar-lib' related tests
     - info: allow user to inhibit creation/update of '${infodir}/dir'
     - warnings: new 'extra-portability' category, for AM_PROG_AR
     - ar-lib: new 'AM_PROG_AR' macro, triggering the 'ar-lib' script
    
    Extra testsuite adjustments:
    * tests/instspc.tap: Adjust to new portability requirements
    due to the new AM_PROG_AR macro.
    * tests/lex-lib.test: Likewise.
    * tests/extra-portability2.test: Use `$am_original_AUTOMAKE'
    instead of the obsolete `$original_AUTOMAKE'.
    * tests/list-of-tests.mk: Update.
