[Findutils-patches] [PATCH 1/8] build: avoid bootstrap error on clean tree

[Bernhard Voelker]

Avoid the following error when running ./bootstrap on a clean tree:

  autoreconf: running: aclocal -I gl/m4 --force -I gl/m4 -I m4
  configure.ac:129: error: AC_PROG_CC cannot be called after AM_PROG_CC_C_O
  ../../lib/m4sugar/m4sh.m4:639: AS_IF is expanded from...
  ../../lib/autoconf/general.m4:1462: AC_ARG_ENABLE is expanded from...
  configure.ac:129: the top level
  autom4te: /usr/bin/m4 failed with exit status: 1
  aclocal: error: echo failed with exit status: 1
  autoreconf: aclocal failed with exit status: 1
  ./bootstrap: autoreconf failed

* configure.ac (compiler-warnings-are-errors): Remove AC_PROG_CC, as this
has already run before and is not allowed at this point anyway.
