Nothing in the build uses LD_LIBRARY_PATH,[*] and it is unlikely for
nbmandoc to have been inadvertently linked against a libc that doesn't
exist yet.  But from your build log, I see:

++ export LD_LIBRARY_PATH=/usr/lib/gcc-snapshot/lib:
++ LD_LIBRARY_PATH=/usr/lib/gcc-snapshot/lib:

Is that in your build environment?  What happens if you remove it?

[*] Exceptions: bsd.test.mk, not relevant here, only in native builds;
    and libexec/httpd/lua/Makefile, for a development-only test
    target, not used automatically as far as I know, and not likely
    relevant to mandoc or libc issues.
