gettext: fix cross compile
For gettext-0.21 cross-compile does not work, because the pre-configure step tries to run `autoreconf -fi`, which fails with the error

    configure.ac:25: error: AC_INIT should be called with package and version arguments
    : gl_AM_INIT_AUTOMAKE is expanded from...
    /usr/share/aclocal-1.16/init.m4:29: AM_INIT_AUTOMAKE is expanded from...
    configure.ac:25: the top level
    autom4te: /usr/bin/m4 failed with exit status: 1
    aclocal: error: /usr/bin/autom4te failed with exit status: 1
    autoreconf: aclocal failed with exit status: 1

This pre-configure step was added back in commit 17f6ad8b for gettext-0.18.3, but its not clear what the error seen back then was, and now cross-compiling without running autoreconf works fine.

So this commit just removes the pre-configure step, reverting 17f6ad8b. This PR fixes #34810.
