[-- Attachment #1: Type: text/plain, Size: 542 bytes --]

The first of these two patches adds support for optional "snippets" to
'package-from-tarball', which is used to unpack the bootstrap tarballs.

The second patch uses this new feature to patch the shebangs in 'egrep'
and 'fgrep' immediately after unpacking the static-binaries bootstrap
tarball.

Obviously, this is for core-updates, the first 2 out of 6 remaining
patches needed for ARM.  It is a prerequisite for ARM support, because
'fgrep' is typically needed for ARM specific tests in configure scripts.

What do you think?

      Mark

I wonder if this should be:

  (begin ,@(if snippet (list snippet) '()))

No big deal though.  OK for this patch.
