[oe] gtk+-native configure fails

[Andreas Müller]

Ciao,

with the latest sources gtk+-nataive (and maybe also gtk+ - but I
don't get that far) configure fails with

| configure.in:1587: warning: PKG_PROG_PKG_CONFIG is m4_require'd but
not m4_defun'd
| aclocal.m4:1818: GTK_DOC_CHECK is expanded from...
| configure.in:1587: the top level
| configure.in:151: error: possibly undefined macro: dnl
|       If this token and others are legitimate, please use m4_pattern_allow.
|       See the Autoconf documentation.
| autoreconf: /home/andreas/tmp/oe-core-eglibc/sysroots/x86_64-linux/usr/bin/autoconf
failed with exit status: 1
| ERROR: autoreconf execution failed.
| ERROR: Function failed: do_configure (see
/home/andreas/tmp/oe-core-eglibc/work/x86_64-linux/gtk+-native-2.24.8-r5/temp/log.do_configure.22156
for further information)

Supporting hints welcome :-)
