[gnutls-devel] [PATCH 2/5] Fix build failures on autogen'ed docs

[Kevin Cernekee]

autogen needs to be invoked with $(srcdir)/<FOO>-args.def or else it
will not be able to find the input file if GnuTLS is built out of tree,
e.g.

    mkdir build
    cd build
    ../configure
    make

Also, add missing targets for %-args.h, to avoid this error:

    make[2]: Entering directory `/home/user/gnutls/src'
    autogen srptool-args.def
    autogen psk-args.def
    make[2]: *** No rule to make target `ocsptool-args.h', needed by `all'.  Stop.
    make[2]: Leaving directory `/home/user/gnutls/src'
    make[1]: *** [all-recursive] Error 1

This change uses a '%'-style pattern to avoid duplication of similar
rules.  '%' patterns are a GNU-ism but there is precedent in
guile/src/Makefile.am.
