Well, good news and bad news. The patch works - this was indeed
a different problem, and with that out of the way ghci comes up
and works well enough to pass some randomly selected tests from a
testsuite - ghci, rts. This is 20080531 plus patch 2013.
The SIGSYS problem is an awkward issue between GHC and NetBSD,
which I see has already been reported, #2305. C code compiled
from /usr/include/signal.h links to __sigprocmask14, but
libraries/base/System/Posix/Internals.hs links to sigprocmask
because it misses out on the __RENAME magic in signal.h. That's
a compatibility function that doesn't work out so well for ghci.
I will take this up with the NetBSD ghc package maintainer. At
worst, we can just hard-code the (incompatibility?) function names.
