Aha, sorry. Does it work if you changes:
-AC_CHECK_PROG(FLOCK, perl, $srcdir/testsuite/flock)
+AC_CHECK_PROG(FLOCK, perl, $ac_abs_srcdir/testsuite/flock)
..., so that this:
> configure: checking for flock implementation
> checking for flock... no
> checking for perl... ../../../gcc/libgomp/testsuite/flock
... turns into an absolute path, to resolve:

... this.
If that works, and you submit a patch, please in the commit log cite this

..., and also specify 'PR testsuite/66005' in the commit log.
If that suggestion doesn't easily resolve this issue, then I'll be able to look
into it next week.
> It appears this problem can be worked around by exporting FLOCK.
But only if that specifies an absolute path (or a "suitable" relative one), I
suppose?
I've also set this "11/12/13 Regression", as these branches use the exact same
code.
