test 44 in B, C, CC: Scalar::Util "weaken" not imported

[GoogleCodeExporter]

# perl #72922 (5.11.4 fails with magic_killbackrefs)
use Scalar::Util "weaken";my $re1=qr/foo/;my $re2=$re1;weaken($re2);print "ok" 
if $re3=qr/$re1/;
>>>
ok 

Problem:
Undefined subroutine &main::weaken called
weaken not imported correctly.

Hacked workaround with r918, which hardcodes Scalar::Util => 
&List::Util::bootstrap

bootstrapping did not detect List::Util, since it is not in its ISA, only 
required. require does not help. (fixed test 44)

Same workaround also needed for 'Sub::Exporter' => 'Params::Util' and probably 
many more.

TODO better strategy for compile-time added and required packages:
  loop savecv and check pkg cache for new pkgs.
  if so loop again with those new pkgs only, until the list of new pkgs is empty
