tools/nolibc: remove local definitions of O_* flags for open/fcntl
The historic nolibc code did not include asm/fcntl.h and had to define the various O_RDWR etc macros in each arch-specific file (since such values differ between certain archs). This was found at least once to induce bugs due to wrong definitions. Let's get rid of all of them and include asm/nolibc.h from sys.h instead. This was verified to work properly on all supported architectures. Signed-off-by: Willy Tarreau <w@1wt.eu> Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
