Avoid bashism in configure script

[okapia]

Currently, the configure script is dumping a log message for the most recent commit into the middle of the output.

&> is non-standard for redirecting stdin and stderr. It is a short-hand copied from csh's >& by zsh and later bash. It is equivalent to >word 2>&1 which will also work in dash (/bin/sh on Debian) or other plain Bourne/POSIX shells.

I would perhaps question whether it might be better to check for the existence of a .git directory instead. Or for a git invocation that does less, perhaps run git rev-parse --git-dir, though that still needs the redirection. Or drop the autoconf test and handle things within the Makefile. Many projects use other forms such as git describe --tags --long --abbrev=7 instead.

thanks,
if you could add DCO it'd be nice

I've pushed a replacement commit with -s for the Signed-off-by trailer to be added.
I didn't find any official text linked from gssproxy (or freeipa) so I'm assuming you're just using the same text as used by Linux (at https://developercertificate.org/). Perhaps this could be made explicit somewhere. Thanks

Thank you, yes github assumes the "standard" DCO as published by the Linux Kernel and we do the same.
