autoreconf is recursive

[Bruno Haible]

Hi Simon and Paul,

The func_create_megatestdir part of this patch

2004-09-18  Simon Josefsson  <address@hidden>
        and  Paul Eggert  <address@hidden>

        * gnulib-tool: Replace various ad-hoc automake/autoconf/aclocal
        calls with autoreconf.  Define GL_LIB.

has the effect of nearly doubling the executing time of
"gnulib-tool --create-megatestdir --dir=/dev/shm/testdir".
4 hours vs. ca. 7 or 8 hours of CPU time - it matters. I'm reverting to
simple autoconf and automake calls for the toplevel directory.

        * gnulib-tool (AUTOMAKEPATH, AUTOCONF, ACLOCAL, AUTOMAKE): New
        variables.
        (func_create_megatestdir): Call aclocal, autoconf, automake here, not
        autoreconf.
