Generate <asm/unistd_x32.h>; this exports x32 system call numbers to
user space.
[ v2: Enclose all arguments to syshdr in '' so empty arguments aren't
dropped on the floor. ]

Split the 64-bit system calls into "64" (64-bit only) and "common"
(64-bit or x32) and add the x32 system call numbers.

On x86, the only difference between sys_rt_sigprocmask and
sys32_rt_sigprocmask is the alignment of the data structures.
However, x86 allows data accesses with arbitrary alignment, and
therefore there is no reason for this code to be different.

Allow the specified syscall offset to be symbolic, e.g. a macro. For
offset system calls, this if nothing else makes the generated code
easier to read.

Simplify syscallhdr.sh by letting grep sort out the ABIs that we want,
rather than relying on manual list matching. This is safe since the
ABI strings already have to consist only of characters which are valid in C
macro names.

Create a simple set of syscall tables and scripts to turn them into
both header files (unistd_*.h) and macros for generating the system
call tables.
