Wire up __NR_perf_counter_open syscall for almost all arches as of

Currently, sysprof hardwires the syscall number of
__NR_perf_counter_open. That's all very well, except... like other
syscall numbers, it varies per-arch. With a few exceptions
(e.g. sparc64), it even varies between 32-bit and 64-bit x86 arches.

This patch provides the defines for every number I could see assigned
in git trunk right now, with the exception of some of the ARM ones, where
I couldn't see how to differentiate between the various sorts of ARM to
figure out what the syscall base was. For those, let's wait for libc to
catch up.

The only arch I've been unable even to guess at is the very new S-Core,
which is the only user so far of the generic syscall table in
<include/asm-generic>. This specifies a value of 241, but I can't hook
it up because I can't find an S-Core toolchain anywhere so I don't know
what #define to check for, and googling gives no clues.

Only tested on x86-64 (where it now works) so there may be all sorts of
bugs in the rest of it (well, in the #defines anyway, though most were
checked against GCC trunk).
