Subject: autogen.sh: Avoid debian buggy which output

Debian's /usr/bin/which after Debian 11 release starts
printing deprecation warning, which causes configure error
("bash not found") when autogen.sh parses output merging
stdout and stderr using 2>&1.

To circumvent this problem, temporarily replace invocation to
which tool with POSIX-compliant "command -v".
