Include generated headers with #include <>

http://www.gnu.org/software/autoconf/manual/html_node/Configuration-Headers.html
“With the appropriate -I option, you can use ‘#include <config.h>’.
Actually, it's a good habit to use it, because in the rare case when
the source directory contains another config.h, the build directory
should be searched first.”
