This series looks pretty good (there are some ""-quote inconsistensies in
some of the smaller-numbered patches, but probably not adding to the
current state of the art -- just note that if these were my patches
that would be intolerable >;D)

So, IMO, the above can be pushed as is (On Fedora 26 the test results
are identical with and without these patches applied (855 succeeded,
7 expected failures, 2 tests skipped on one of my systems)

This last one (in addition to quote inconsistencies) has also slight
naming inconsistency compared w/ other files in that directory; To match
IMO this should be named as check-out-of-tree-build.sh... And since
I had to comment on this I'll express my nitpicks of the content, too :D:

quotes unnecessary above, but may clarify things...

... but the above is then inconsistent as it does not have ""-quotes

due to $(mktemp -d) not outputting any $IFS characters the above always
works without "$builddir" but imo not having quotes there is a bad example
(and inconsistent to what I'm going to write below)

$srcdir, OTOH could have $IFS characters (usually spaces) there, so above
line would break in such a case

ditto
