Bug#793121: ocaml-fdkaac: FTBFS in pbuilder: error: configure script must not be run with root user!

[Andreas Beckmann <anbe@debian.org>]

Package: ocaml-fdkaac
Version: 0.2.0-1
Severity: serious
Justification: fails to build from source

ocaml-fdkaac fails to build in pbuilder. I don't know if it fails in
sbuild as well, since I don't have a sbuild setup.
Since the package is in non-free and has Build-Depends from non-free
as well it cannot be built on the buildd network and is also not
tested by the regular archive wide rebuild tests, so this bug has gone
unnoticed for some time.

pbuilder is definitively not running the build as root, so 
that check for root seems to be bogus.

Trying to refresh the build system does not work:

ocaml-fdkaac-0.2.0$ autoreconf -f -i
configure.ac:8: error: possibly undefined macro: AC_BASE_CHECKS
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
