Add support for Imagination Technologies Meta architecture (the
architecture/ABI is usually referred to as metag in code). The Meta
Linux kernel port is in the process of being upstreamed for v3.9 so it
uses generic system call numbers.
sys_lookup_dcookie writes a filename to buffer argument, so I've set
TF flag.
nfsservctl appears to be set to sys_ni_syscall in asm-generic/unistd.h
so I've left it blank.
truncate64/ftruncate64/pread64/pwrite64/readahead have unaligned 64bit
args which are packed tightly on metag, so less arguments on metag.
fchdir/llseek takes a file descriptor so s/TF/TD/
sync_file_range has 2 64bit args so uses 6 args, so s/4/6/
timerfd_create/msgget/msgctl/msgrcv/semget/segtimedop/semop/shmget/
shmctl/shmat/shmdt/recvmsg/migrate_pages have different number of args.
oldgetrlimit is just getrlimit for metag.
add TM flag to various memory syscalls.
metag doesn't directly use sys_mmap_pgoff for mmap2.
prlimit64/process_vm_readv/process_vm_writev take a pid so add TP flag.
fanotify_init doesn't appear to take a file descriptor so remove TD.
Add kcmp syscall.

X32 support is added to Linux kernel 3.4. In a nutshell, x32 is x86-64 with
32bit pointers. At system call level, x32 is also identical to x86-64,
as shown by many changes like "defined(X86_64) || defined(X32)". The
main differerence bewteen x32 and x86-64 is off_t in x32 is long long
instead of long.

The long long endian detection code does an AC_TRY_RUN() and since that
doesn't work when cross-compiling, it sets a fallback value. However,
rather than do any sort of default endian detection, the code simply
sets it to "no". This probably breaks most little endian systems out
there when cross-compiling for them. It certainly breaks Blackfin
systems. So use the common endian detection code provided by autoconf
and key off of that when cross-compiling.
* configure.ac: Call AC_C_BIGENDIAN.

logic based on ac_cv_c_bigendian.
