Subject: [PATCH] iconv: tweak iconv detection

Tweak PHP_SETUP_ICONV from aclocal/build/php.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.
