[OpenIndiana-discuss] btop illumos/OpenIndiana port — PR up, looking for testers

[Alex Gorouvein]

Peter,

All four points fixed and pushed to GitHub:

- CPU panel on SPARC: was probing kstat instances 0..N-1 by number,
assuming contiguous zero-based ids. Now walks the live kstat chain instead,
so it doesn't matter what range the ids fall in.
- fs/sys/buf.h collision: alias renamed to btop_fs.
- find/getconf NPROCESSORS_ONLN: source discovery now uses Make's built-in
$(wildcard ...) instead of find; thread count tries psrinfo first, getconf
as fallback.
- -static-libstdc++: no longer forced, only added for the Solaris 10
cross-build (S10=true).

Tested on an OpenIndiana VM and Solaris 10 x86 VM so far; still need to
re-run this batch on bare metal, an old Acer laptop with OI, which I'll get
to shortly. Please let me know how it goes on your SPARC machines.

Thanks again for the testing.

Alex
