Hmm, OK, so if I am reading the log correctly the addr2line failures are
happening because running:

   addr2line -e tmpdir/testprog <some address>

returns:

   ./builddir-single/binutils/./binutils/testsuite/binutils-all/testprog.c:<some line number>

whereas the regexp is expecting to match:

  "$srcdir/$subdir/testprog.c:\[0-9\]+"

which translates to:

   /home/packages/binutils/binutils-2.40.50.20230628/binutils/testsuite/binutils-all/testprog.c:[0-9]+

Looking back in the log I notice that the test program is being compiled
with:

   x86_64-linux-gnu-gcc \
    /home/packages/binutils/binutils-2.40.50.20230628/binutils/testsuite/binutils-all/testprog.c \
    -g \
    -O2 \
    -ffile-prefix-map=/home/packages/binutils/binutils-2.40.50.20230628=. \
    -O0 \
    -g \
    -lm \
    -o tmpdir/testprog

(I added the backslash line separators).

And so the culprit appears to be the -ffile-prefix-map... option.  Which I think
must be coming from your environment as it is not a normal part of the binutils
testsuite.

Does this make sense ?

I suspect that the same problem explains why the objdump+source+listing tests
are failing.  The sources are not where the built binaries are saying that they
should be.

Cheers
