php: fix iconv related build failure

Fix a rare edge build failure when iconv is enabled, easily reproduced
in a debian chroot with an aarch64 external toolchain with iconv +
xmlrpc support enabled with a php cgi + cli target.
Should solve bug #6500.

+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.

-Don't push LDFLAGS/CFLAGS for iconv.
-Just assume they're covered somewhere else.
-Otherwise we get -L/usr/lib and -I/usr/include search paths with uClibc
-internal iconv support, which breaks things.
