./configure: line 9178: syntax error near unexpected token `LIBGNUTLS, '

[Hans-Christoph Steiner]

I'm getting this while building the latest GnuPG for Android using gnupg 2.1.1:

  checking for NTBTLS - version >= 0.1.0... no
  ./configure: line 9178: syntax error near unexpected token `LIBGNUTLS,'
  ./configure: line 9178: `    PKG_CHECK_MODULES(LIBGNUTLS, gnutls >=
$NEED_GNUTLS_VERSION,'
  make: *** [gnupg/Makefile] Error 2

I'm not really sure the exact trigger for this, but on one Debian/stable
machine, I get this problem reliably, while on another Debian/stable machine,
I do not.  But I think I can see the cause, at line 858 in configure.ac:

  if test x"$try_gnutls" = xyes ; then
    PKG_CHECK_MODULES([LIBGNUTLS], [gnutls >= $NEED_GNUTLS_VERSION],
                                   [have_gnutls=yes],
                                   [have_gnutls=no])
  fi

Which looks like this in ./configure:

  if test x"$try_gnutls" = xyes ; then
    PKG_CHECK_MODULES(LIBGNUTLS, gnutls >= $NEED_GNUTLS_VERSION,
                                   have_gnutls=yes,
                                   have_gnutls=no)
  fi

Here, PKG_CHECK_MODULES() is being included as a sh function rather than an
autoconf macro.  As far as I know, it is not valid sh syntax to have a
function call with parens spanning multiple lines.  I attached the
config.log and log of the build itself.  The generic ./configure script is too
big to attach for this list's strict, tiny 40kb limit, so it is here:
