Avoid duplicate definition of global default variables

With GCC 10 several things got changed. One of the things is the
-fno-common default which prevented the code to link cause of multiple
definition issues.
Declared the variables extern and defined them in c-file to avoid the linker error.
Details can be found here: https://gcc.gnu.org/gcc-10/porting_to.html
