Direct socket syscalls have been added in kernel 4.4 on sparc for
bind, listen and setsockopt. Other direct socket syscalls were present
before kernel 3.2 and are listed directly in syscalls.list, so there is
no need to add them there.
Changelog:
* sysdeps/unix/sysv/linux/sparc/kernel-features.h
[__LINUX_KERNEL_VERSION >= 0x040400] (__ASSUME_BIND_SYSCALL):
New macro.
[__LINUX_KERNEL_VERSION >= 0x040400] (__ASSUME_LISTEN_SYSCALL):
Likewise.
[__LINUX_KERNEL_VERSION >= 0x040400] (__ASSUME_SETSOCKOPT_SYSCALL):
Likewise.
