Douglas Bagnall 068b366709 buildtools:pidl: avoid hash randomisation in pidl 
Like many languages, Perl uses has randomisation to prevent nasty
users using crafted values that hash to the same number to effect a
denial of service. This means the traversal order of perl HASH tables
is different every time.

The IDL handed to pidl is trusted, so we don't really need
randomisation, but we do want to be sure the build is the same every
time.

I am not aware of hash randomisation causing problems, but it seems
prudent to avoid it.

We do a similar thing with PYTHONHASHSEED for the entire build.

Thanks to Freexian and the Debian LTS project for sponsoring this work.

README 

This is a set of waf 'tools' to help make building the Samba
components easier, by having common functions in one place. This gives
us a more consistent build, and ensures that our project rules are
obeyed
