* sysdeps/unix/sysv/linux/arm/sys/user.h: Added members
'unsigned char ftype[8]', and 'unsigned int init_flag' to
struct user_fp. Tnese were added in version 2.2.12 of the
ARM Linux kernel.
* sysdeps/unix/sysv/linux/arm/sys/elf.h: New file.
* sysdeps/unix/sysv/linux/arm/sys/procfs.h: New file.
The generic procfs.h included <asm/elf.h>. This causes
structure redefinition errors when <sys/user.h> and
<sys/procfs.h> are included in the same source file. Found
when building GDB.
