6.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Willy Tarreau <w@1wt.eu>

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.

Fixes: feaf75658783a ("nolibc: fix fd_set type")
