[PATCH] configure.ac: fix syntax error in ./configure

[Alejandro Mery]

dnl eats the new line between both statements

./configure: line 2815: syntax error near unexpected token `ac_config_headers="$ac_config_headers config.h"'
./configure: line 2815: `fi ac_config_headers="$ac_config_headers config.h"'

this is still a problem with autoconf 2.69 compiling libev-4.19 from sources

autoconf 2.69 on Ubuntu 14.04.1 LTS x86_64

thanks,
Alejandro Mery
