Latest libc++[1] causes transitive include to <locale> when <mutex> or <thread> header is included. This causes gdb to not build[2] since <locale> defines isupper/islower etc. functions that are explicitly macroed-out in safe-ctype.h to prevent their use. Use the suggestion from libc++ to include <locale> internally when building in C++ mode to avoid build errors. Use safe-gdb-ctype.h as the include instead of "safe-ctype.h" to keep this isolated to gdb since rest of binutils does not seem to use much C++.
