A patch for db4.8 on gcc8+

The march of "progress" sometimes brings about a lot of headaches, especially when I am forced to work on heathen systems such as Debian and Ubuntu. This became readily apparent while installing bitcoind (core) to a server equipped with gcc-9.1.0 this past week. While building the dependencies, db-4.8.30.NC promptly shat out this error:
definition of 'int __atomic_compare_exchange(db_atomic_t*, atomic_value_t, atomic_value_t)' ambiguates built-in declaration 'bool __atomic_compare_exchange(long unsigned int, volatile void*, void*, void*, int, int)' static inline int __atomic_compare_exchange
A relatively simple patch allowed me continue building error-free. I have included in the /library/ here for future reference. Place it in the root of the db-4.8.30.NC folder and apply manually as you would any other patch.
While impossible to completely rid the world of such fuckery, I consider this just another tool in the box to make things slightly less painful
