No feedback in over 6 months on the exact command line which is failing,
assuming a bug in the build system of cmake.

>[ 88%] Linking CXX executable ../bin/ccmake


Can you provide the full linking command line rather than this non-verbose
output?

This actually usually means some shared library has been linked without linking
against -lgcc_s or -lgcc (common reason is e.g. linking with ld -shared instead
of gcc -shared or g++ -shared) and you are trying to link against that shared
library.

To relay a comment on the netbsd bug,
"I don't think (the proposed idea) is correct and the real problem is that we
are linking libgcc first (again)."

Maybe expose __clz_tab but only in the fallback definition case, and not make
it hidden.
