Subject: tests: avoid missing .dvi failure with parallel tests
X-Git-Tag: v1.16.3~5
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=17e6f26a581b94254206a1ce6e3de10e5fed0dc8;p=thirdparty%2Fautomake.git

tests: avoid missing .dvi failure with parallel tests

* t/txinfo-no-clutter.sh: Tests of texinfo-related rules
had overlap that made them fail often when some rules were
run in parallel, so inhibit parallelism in that one directory.
