patch: Makefile.in in subdir not generated

[Ilya N. Golubev]

Described what is fixing here in <Makefile.in in subdir not
generated> posted to <address@hidden> on
generated> (<address@hidden>).

Patched 1.10.1 as follows.

        * lib/am/configure.am (%MAKEFILE-IN%): Fixed `exit'ing before
        invoking `$(AUTOMAKE)' if prerequisite other then
        `Makefile.am' is newer.  Borrowed invocation of recursive
        `make' and handling its exit codes from commands generated by
        automake for other recursive targets.  Added elimination of
        duplicate `$(AUTOMAKE)' invocation.
