[SV 60378] Don't add duplicate default search directories
Depending on how make was configured it may add duplicate
directories in the default include search path: avoid this.
(Tweaked by psmith@gnu.org)
* configure.ac: Set AM variable KNOWN_PREFIX if --prefix is known
* Makefile.am: Only set INCLUDEDIR if prefix is not known
* read.c [default_include_directories]: Only add INCLUDEDIR if set
