There are some differences between rtmp check and libssh2 one in configure.ac :

1) rtmp :

  case "$OPT_LIBRTMP" in
  yes)
    dnl --with-librtmp (without path) used
    CURL_CHECK_PKGCONFIG(librtmp)

    if test "$PKGCONFIG" != "no" ; then
      LIB_RTMP=`$PKGCONFIG --libs-only-l librtmp`
      LD_RTMP=`$PKGCONFIG --libs-only-L librtmp`
      CPP_RTMP=`$PKGCONFIG --cflags-only-I librtmp`
      version=`$PKGCONFIG --modversion librtmp`
      DIR_RTMP=`echo $LD_RTMP | $SED -e 's/-L//'`
    else
      dnl To avoid link errors, we do not allow --librtmp without
      dnl a pkgconfig file
      AC_MSG_ERROR([--librtmp was specified but could not find librtmp
pkgconfig file.])
    fi

2) libssh2 :

  case "$OPT_LIBSSH2" in
  yes)
    dnl --with-libssh2 (without path) used
    CURL_CHECK_PKGCONFIG(libssh2)

    if test "$PKGCONFIG" != "no" ; then
      LIB_SSH2=`$PKGCONFIG --libs-only-l libssh2`
      LD_SSH2=`$PKGCONFIG --libs-only-L libssh2`
      CPP_SSH2=`$PKGCONFIG --cflags-only-I libssh2`
      version=`$PKGCONFIG --modversion libssh2`
      DIR_SSH2=`echo $LD_SSH2 | $SED -e 's/-L//'`
    fi

that is, no 'else' branch in libssh2 check.

As I don't know what you want to achieve, i have no patch to propose.
But I find that configure.ac file really too complicated.
