Bug#722565: visp: test suite needs -j1

[Sebastian Ramacher]

Source: visp
Version: 2.8.0-1
Severity: important

Some of the checks in the test suite can not be run in parallel. Running
with -j5 fails for me with:
|         Start   9: displayGDI
|         Start  10: displayD3D
|         Start  11: displayGTK
|         Start  12: displayX
|   8/105 Test  #12: displayX .....................................***Failed    0.04 sec
| libdc1394 error: Failed to initialize libdc1394
| !!      /«PKGBUILDDIR»/src/tools/io/vpIoTools.cpp: makeDirectory(#432) :unable to create directory '/tmp/sebastian'
|
| !!      /«PKGBUILDDIR»/src/tools/io/vpIoTools.cpp: makeDirectory(#465) :unable to create directory '/tmp/sebastian'
...
| 99% tests passed, 1 tests failed out of 105
|
| Total Test time (real) =  16.12 sec
|
| The following tests FAILED:
|          12 - displayX (Failed)
| Errors while running CTest
| make[2]: *** [test] Error 8

It's either displayX or displayGTK that fails. With -j1 everything works
as expected. So parallel execution needs to be disabled for the test
suite.
