bug#29940: Acknowledgement (guile-2.2.3 does not work pax mprotect)

The attached patch is a workaround: we can mark the guile binary to
not use the PAX mprotect feature using paxctl +m. On Linux, paxctl has
different flags, so I wrapped it in an "if", and it uses knowledge of
libtool internals, so it is not a good idea to integrate this patch
as-is.

Better would be of course to make guile work with PAX mprotect.
