uclibc++: remove
No package here depends on it. Furthermore, uClibc++ is a fairly buggy C++ library and seems to be relatively inactive upstream. It also lacks proper support for modern C++11 features. The main benefit of it is size: 66.6 KB vs 287.3 KB on mips24kc. Static linking and LTO can help bring the size down of packages that need it. Added warning message to uclibc++.mk Signed-off-by: Rosen Penev <rosenp@gmail.com> Acked-by: Hauke Mehrtens <hauke@hauke-m.de>

-Subject: [PATCH] cstdio: Add undef for four functions
-
-When compiling with uClibc-ng, these functions get defined as macros and
-become unavailable for std.
-
-Fixes programs that use the std versions of these functions.
-
-This matches libstdcpp behavior.
