uClibc++: Fix three bugs The first allows usage of several functions in the std namespace, which broke compilation of gddrescue specifically with uClibc-ng and uClibc++. The second allows usage of long long with normal C++11, which is part of the standard. Before, std=gnu++11 needed to be passsed to work around it. As a result of the second patch, the pedantic patch can safely be removed. Both patches are upstream backports. Added -std=c++11 to CFLAGS to guarentee proper inclusion of long long. Added another patch that fixes a typo with the long long support. Sent to upstream. Fixed up license information according to SPDX. Small cleanups for consistency.
