(In reply to Mark Millard from comment #17)

The following seem to explain the:

ld-elf.so.1: /lib/libgcc_s.so.1: version GCC_4.5.0 required by
/usr/local/lib/gcc11/libstdc++.so.6

On aarch64 there is such a reference involved:

# nm -a /usr/local/lib/gcc11/libstdc++.so.6 | grep @GCC_4
                 U _Unwind_GetIPInfo@GCC_4.2.0
                 U __floatunditf@GCC_4.2.0
                 U __unordtf2@GCC_4.5.0

The fluxengine examples indicate that other code generation can
also produce @GCC_4.5.0 references in other files. I've not
checked if it is only __unordtf2 that is referenced.
