tests: fix spurious failure due to missing sleeps Fixes automake bug#14528. * THANKS: Give credit to that bug's original reporter. * t/remake-configure-dependencies.sh: Add few missing '$sleep' invocations. I thought that the sleeps implicit in the configure invocation were enough, but they were not, actually. Here is what can happen: 1. The config.status script is generated by a configure run. 2. ./config.status and make are run. 3. The 'print-version' script is modified. 4. Since that script is listed in $(CONFIGURE_DEPENDENCIES), autoconf is re-run. 5. On a fast-enough machine, the three steps 2-4 above, even combined, might have taken less than a second to run; 6. If the filesystem doesn't have a sub-second timestamp resolution, that means the newly-generated configure has the same timestamp of the old config.status; 7. So, config.status is not re-run, and the Makefiles are not updated. 8. Spurious failure! So we really need more explicit sleeps. Signed-off-by: Stefano Lattarini <stefano.lattarini@gmail.com>
