Subject: tests: some tests make no sense if "$CC -c -o" doesn't work
X-Git-Tag: v1.13b~14^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b2b6269fca6f7bb7adac2d09c02adf0c6b701d48;p=thirdparty%2Fautomake.git

tests: some tests make no sense if "$CC -c -o" doesn't work

So just skip them, to avoid spurious failures when running
"make check-no-cc-c-o".

* t/ax/am-test-lib.sh (require_tool): New requirement '-c-o'.
* t/subobj10.sh ($required): Add it.
* gen-testsuite-part (%depmodes): Adjust so that tests that
use 'makedepend' will be skipped if the compiler is being
forced not to grasp "-c -o".
