Ok, I found the source of the problem.
Some tests use imake; they create a new subdir in /tmp/imake.$$ and a
simple Imakefile like:

#if BuildFreetype2Library
builtin-test:
        @echo yes
#else
builtin-test:
        @echo no
#endif

When I manually cd into that directory and run the command from
mk/buildlink3/imake-check, it has random failures.
The first part of the command is:
# imake -DUseInstalled -I/usr/X11R7/lib/X11/config -s - 
When I run this multiple times in a row, most of the time it produces
a long makefile as output, but sometimes it just prints nothing. At
all.

So for example:
# imake -DUseInstalled -I/usr/X11R7/lib/X11/config -s - | make -f - 
builtin-test 
make: don't know how to make builtin-test. Stop

make: stopped in /tmp/imake-check.28859
# imake -DUseInstalled -I/usr/X11R7/lib/X11/config -s - | make -f - 
builtin-test 
yes

The same command twice in a row.

That's on 5.99.53 from today with /tmp a tmpfs (in a sandbox that's
selectively nullmounted from '/').
