This part of buildworld uses the compiler, include files, linker and
libraries from your existing system. E.g. it is normal for this part to
use /usr/bin/ld, /usr/lib, and so on.
On a 9.3 system, I would not expect ld to search for libc_nonshared.a,
since that is a feature introduced in 10.0, where /usr/lib/libc.so was
changed from a symlink to a linker script.
Can you please check on your system, what /usr/lib/libc.so is? Is it a
symlink or a plain text file? If it is the latter, your system is most
likely polluted with 10.x installation left-overs.

For the early stages of buildworld, e.g. bootstrap-tools, build-tools
and cross-tools, it is normal that the system compiler is used, e.g.
just /usr/bin/cc.
On a 9.x system, that is usually gcc, but this does not say anything
about the later stages of buildworld, which will be built with the
toolchain produced in the cross-tools stage. For 10.x, that is usually
clang.

I think it is better to inspect your /usr/lib/libc.so, and find out if
it is accidentally replaced by a linker script.

During the early stages of buildworld, this is completely normal, and
expected.
