devel/grantlee5: fix build with GCC architectures

Compiling with GCC9 fails with:
/usr/local/lib/gcc9/include/c++/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

Add USE_CXXSTD=c++11 to fix this.
