I was tripped up by this same issue, and was not easily able to figure
out from the autoconf documentation how AC_INIT had changed over time.
The one-argument AC_INIT, for the version of autoconf I was using
(2.57), expects its argument to be a path to a file that is relatively
unique to the package.

However, this isn't actually related to the problem at hand:

This is a shell programming error.  Remove the '\' inside your quoted
--configure-args argument.  The backslash causes the newline to be
escaped in the string passed to the configure script, which confuses
the argument parser.  You don't need the backslash because a quoted
string is automatically continued until the closing quote is seen.
