To allow a different implementation than the GCC built-ins, for certain functions and architectures. To allow extensions (i.e. atomic functions that aren't GCC built-ins) in a clean way. To avoid using GCC built-ins directly, both for cosmetic reasons, and that it might cause problem for future compilers.
