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.
