[scc-dev] [PATCH] tests/cc: Fix 0225-func.c pointer type

According to C99 6.4.2.2p1, __func__ is declared as array of const
char, so when used as an initializer, it is converted to const char *.

An initializer for a scalar follows the same type constraints as
simple assignment, which for pointers requires that both are to
compatible types, and char and const char are not compatible since
the have different qualifiers.
