Bug#670733: ocaml-cry: FTBFS: Incorrectly thinks it's building as root

[Hendrik Tews <hendrik@askra.de>]

... the incorrect root test comes from file m4/base_checks.m4

deleting the line 'RUNNING_USER="$USER"' there and running
./bootstrap then yields 

  checking that calling user is not root... ok

and the package builds fine (done with autoconf 2.69; maybe its
better to downgrade to 2.68 to keep the patch small).

Bye,

Hendrik
