Hi!

guile-2.2.3 does not compile on NetBSD 8 and NetBSD-current.
During build, it writes stuff like this for basically every file:

gmake[2]: Entering directory '/scratch/lang/guile22/work/guile-2.2.3/bootstrap'
  BOOTSTRAP GUILEC ice-9/eval.go
;;; WARNING: loading compiled file /scratch/lang/guile22/work/guile-2.2.3/prebuilt/64-bit-little-endian/ice-9/eval.go failed:
;;; Throw to key system-error with args ("load-thunk-from-memory" "~A" ("Permission denied") (13))
wrote `ice-9/eval.go'

When I turn off PaX mprotect, the build succeeds.

PaX mprotect is a security feature that forbids memory pages that are
writable and executable, and some memory protection changes that would
allow this. Other programs/libraries (e.g. libffi) needed to be fixed
for this.

Can you please fix this in guile-2.2.x?
(guile-2.0.14 builds fine on such a system.)

Thanks,
 Thomas
