I am guessing vax is missing an implementation of __builtin_clz
and cmake is using it (in ./Utilities/cmliblzma/common/tuklib_integer.h).
It has a fallback for older compilers which you can use

Looking at GCC include/longlong.h, most archs have a
count_leading_zeros. vax does not.
the fallback implementation references __clz_tab, which has hidden
visibility.

I don't think the patch is correct and the real problem is that we are linking libgcc first (again).

The attached (untested but straightforward) patch changes the link
order to verify if joerg's hunch is correct.
I don't think it should be committed as-is, but please try it out so
we know.
It's against -current's src/external/gpl3/gcc/dist/gcc/gcc.c.
Thanks,
Thomas

I am currently testing a slightly simpler variant of the patch for
the gobject-introspection issue.

State-Changed-Why:
Feedback was received, long ago.
I am inclined to just close this because cmake changes rapidly and the
problem is from 2017. i'm also sort of surprised it's possible to build
cmake on a vax at all...
However, I'll leave it open for the moment; if the issue is still interesting
and/or anyone has any input as to whether it's still current, let me know.
Otherwise it'll probably get closed in some future sweep...

It is no longer a problem. IIRC, changes by joerg@ in 2017 fixed things.
