The configure sends a link, but I can’t find the source to compile out of that, neither can I understand, what
the “smoke” test is.

The link shows a source of a C program whose first line says:

 Smoketest example for libgccjit.so

I tried to follow the instruktions, but god lost underway….

You mean, the instructions on the URL how to compile the test program?
They are quite simple: 2 shell commands.

Anyway, I've modified that error message to say this instead:

 The installed libgccjit failed to compile and run a test program using
 the libgccjit library; see config.log for the details of the failure.
 The test program can be found here:
 <https://gcc.gnu.org/onlinedocs/jit/intro/tutorial01.html>.

Just a small note, the smoke test we run from the configure is not
exactly the one of the link as we just compile a function returning an
integer.  Needless to say that most certainly if one works the other
will too.
