+Tweak PHP_SETUP_ICONV from aclocal/acinclude.m4 to not
+PHP_ADD_INCLUDE $ICONV_DIR/include since the tests use
+test instead of AC_TRY_LINK to find headers which is bad,
+specially when adding /usr and /usr/local to the mix.
+Do basically the same with ext/iconv/config.m4 by tweaking
+PHP_ICONV_H_PATH which, again, uses test and absolute paths.
