ISC_PLATFORM_USEBACKTRACE

[Gary E. Miller]

Yo Hal!

Check out commit 99df9ac91a01a254ca19bbf72d1c2f0fe297d522

It has code to print out the failed syscall #. At least on some OS.
I'll see which fail and then blacklist them.  So far it seems to work on
all the buildbot workers.  I can't believe that is right...

Notice no need for backtrace().  In fact, I spent some more time
with backtrace().  The failed syscall is never in the backtrace, so
backtrace would be useless here.

AFAIK, the isc_backtrace never did anything useful.  BUT, at least
with gcc I see a way to make it useful,  I'll get back to that, after
I finish up on your seccomp issue.
