MDEV-9943 - TokuDB fails to compile with gcc 5.2.1

For some reason check_cxx_compiler_flag() passes result variable name down to compiler: https://github.com/Kitware/CMake/blob/master/Modules/CheckCXXSourceCompiles....

But compiler doesn't permit dashes in macro name, like in -DHAVE_CXX_-fimplicit-templates.

Workarounded by renaming HAVE_CXX_-fimplicit-templates to HAVE_CXX_IMPLICIT_TEMPLAES.

I'd rather fix other similar places too. If you agree, ok to push with the patch below.
