Add -fcommon to CFLAGS

CLANG has changed its default behaviour by setting -fno-common as the default
option, to meet GCC10 behaviour:

"[...] With this change, C code that uses tentative definitions as definitions
of a variable in multiple translation units will trigger multiple-definition
linker errors. Generally, this occurs when the use of the extern keyword is
neglected in the declaration of a variable in a header file. In some cases, no
specific translation unit provides a definition of the variable. The previous
behavior can be restored by specifying -fcommon. [...]

(see: https://reviews.llvm.org/D75056)

As a "quick and dirty" workaround I added -fcommon to CFALGS to restore the
previous behaviour. A more sophisticated solution (which implies a deeper
insight into the codebase of refdb) would be desireable.

Additionaly, I allowed to change the E-Mail address.
