[PATCH 27/29] [AARCH64] Fix up ucontext for ILP32

[Andrew Pinski]

In ILP32 we want to use the same layout of the structure ucontext as LP64 so
we need to add a padding for uc_link and change the type of uc_flags to
be the kernel unsigned long type.

* sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h (struct ucontext):
Change the type of uc_flags to __SYSCALL_ULONG_TYPE.
Add padding for uc_link if ILP32.
