Spotted when inspecting gcc testsuite logs, but this already is
covered by the ld-mmix testsuite, it's just that the assert is ignored
since the regexp match is for a substring and not anchored.
With the anchors added but not the bugfix, the ld.log shows that the
asserts cause a non-match as intended:
Executing on host: sh -c {./ld-new -LX/src/ld/testsuite/ld-mmix -m elf64mmix -o tmpdir/dump tmpdir/undef-2.o tmpdir/start.o 2>&1} /dev/null dump.tmp (timeout = 300)

Gone with the fix of course, leaving just the intended "undefined
reference" like.
I'm not going to add anchors manually for all the "error:" strings in
the test-suite, not even in the mmix parts. Sorry, but I'll just do
it for *these* specific undefined-reference tests.
Just a thought: maybe the run_dump_test "error:" string should
*automatically* get anchor marks prepended and appended for a single
line match as in the patch, "\A[^\n\r]*" prepended and \Z appended
unless either anchor mark or \r or \n is present in the regexp?
Committed.
bfd:
* elf64-mmix.c (mmix_elf_relax_section): Improve accounting for
R_MMIX_PUSHJ_STUBBABLE relocs against undefined symbols.
ld/testsuite:
* testsuite/ld-mmix/undef-1.d, testsuite/ld-mmix/undef-1m.d,
testsuite/ld-mmix/undef-2.d, testsuite/ld-mmix/undef-2m.d: Add
start- and end-anchors to error-string to match just a
single-line error-message.

BFD is an object file library. It permits applications to use the
same routines to process object files regardless of their format.
BFD is used by the GNU debugger, assembler, linker, and the binary
utilities.
The documentation on using BFD is scanty and may be occasionally
incorrect. Pointers to documentation problems, or an entirely
rewritten manual, would be appreciated.
There is some BFD internals documentation in doc/bfdint.texi which may
help programmers who want to modify BFD.
BFD is normally built as part of another package. See the build
instructions for that package, probably in a README file in the
appropriate directory.
BFD supports the following configure options:
--target=TARGET
The default target for which to build the library. TARGET is
a configuration target triplet, such as sparc-sun-solaris.
--enable-targets=TARGET,TARGET,TARGET...
Additional targets the library should support. To include
support for all known targets, use --enable-targets=all.
--enable-64-bit-bfd
Include support for 64 bit targets. This is automatically
turned on if you explicitly request a 64 bit target, but not
for --enable-targets=all. This requires a compiler with a 64
bit integer type, such as gcc.
--enable-shared
Build BFD as a shared library.
--with-mmap
Use mmap when accessing files. This is faster on some hosts,
but slower on others. It may not work on all hosts.
Report bugs with BFD to bug-binutils@gnu.org.
Patches are encouraged. When sending patches, always send the output
of diff -u or diff -c from the original file to the new file. Do not
send default diff output. Do not make the diff from the new file to
the original file. Remember that any patch must not break other
systems. Remember that BFD must support cross compilation from any
host to any target, so patches which use ``#ifdef HOST'' are not
acceptable. Please also read the ``Reporting Bugs'' section of the
gcc manual.
Bug reports without patches will be remembered, but they may never get
fixed until somebody volunteers to fix them.
