commit a477629baa2a0e9991f640af418e8c973a1c08e3 upstream.
While nolibc-test does test syscalls, it doesn't test as much the rest of the macros, and a wrong spelling of FD_SETBITMASK in commit feaf75658783a broke programs using either FD_SET() or FD_CLR() without being noticed. Let's fix these macros.
