bug#11452: self test failure: t/parallel-tests-fork-bomb

[Simon Josefsson]

I got two self-test failures with automake 1.12 on Ubuntu 12.04 LTS.
The first was the 'lex-clean' issue that was already reported.  The
other I couldn't find any report for, so please find test-suite.log
output for the failing test below.
