Ticket #3753: extfs: tester: let test scripts easily access configure-time parameters.
We introduce a mechanism by which tests can easily access configure-time
parameters (like @PERL@, @AWK@, ...).
It works by "sourcing" a file named config.sh (residing in the build tree):
. "$MC_TEST_EXTFS_CONFIG_SH"
$PERL -e 'print "hello"'
(Although config.sh has a shell syntax, Perl and Python programs too can
benefit from it, because it can be sourced into an .env_vars file and the
values exported from there.)
Of course, one can also use the traditional method, of *.in files listed in
configure.ac, but the mechanism introduced here is a more comfortable approach.
