Subject: use Python 3 compatible syntax in autotools check
X-Git-Tag: 2.44.1~55^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b308bc031dbeb3b0af1f71d293b98b8048b2ac94;p=graphviz

use Python 3 compatible syntax in autotools check

We expect `python` to be a symlink to Python 3, not Python 2 but it does not
hurt to use syntax compatible with both. Other Python checks in configure.ac
were already using compatible syntax.

Fixes #1626.
