There are two different syscall names for the same goal.
On systems with sizeof(long) == 64 it calls newfstatat.
On systems with sizeof(long) == 32 it calls fstatat64.

The sys_inotify* calls are defined if the target supports them and the
host supports the necessary syscalls. But the syscalls are handled if
the target supports them. This situation leads to compilation failures
when the host doesn't support the necessary syscalls, as the linker will
complain about undefined functions.
Fix this state of affairs by making the handling conditions the same as
the call definition conditions.

This patch implemented the setxuid and setxgid syscalls for Alpha.
These syscalls return two values, both uid/euid and gid/egid.
In addition to returning the first value in $v0, the additional
value is returned in the $a4 register.
The syscalls are used instead of the separate syscalls for those values
used on other architectures (this is probably because Alpha Linux started
out syscall compatible with DEC/OSF/Tru64).
With this patch, the perlbmk benchmarks from Spec2000 run properly.

glibc's structs dirent and dirent64 is different from in-kernel dirent
and dirent64. Kernel headers doesn't provide structs dirent(64) any
more. So we should add it to qemu headers.
To avoid conflict with glibc it called struct linux_dirent(64).
