This is a bug in hotspot/make/test/JtregNative.gmk. A library parameter
like -ldl should be set to a LIBS variable and not LDFLAGS. Our default
gcc does not react to this, but later versions do, which is why these
bugs tend to sneak in.

I think the problem is caused by a quirk in my gcc - if I compile
something with
gcc -ldl foo.cpp
it fails with messages similar to the one I mentioned. To make it work
I have to do:
gcc foo.cpp -ldl
On the other hand, the gcc version included in the dev toolkit works
with both variants.

Using the devkit worked - but this is odd as it was working as of
last week, and it seems like the linker gets passed the flag -ldl
which you need to avoid this kind of issues (and I do have libdl.so
installed).

To work around it, you should be able to run something like this:
$ make build-test-jdk-jtreg-native jdk-image && make test-only
TEST=jdk_util
Maybe you also need build-test-failure-handler and build-test-lib.
Not sure.
No luck - that fails with this:
Error: Cannot find observer class:
jdk.test.failurehandler.jtreg.GatherDiagnosticInfoObserver

Any idea of what is wrong? My spec.gmk points to the latest jtreg
(I ran configure with --with-jtreg)
Thanks
