-Just assume ICONV_DIR is fine since we pass the correct parameters
-to configure.
-Otherwise configure will try to guess on absolute directories and
-sometimes messes up on some weird edge conditions.
+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.
+And all this directly in configure since autoreconf isn't
+happy with php.
