Would

    $ make LINK_FUZZ_PROGRAMS=""

help?

The platform-specific tweak defined in config.mak.uname file assumes that you have glibc plus gcc or clang with usual binutils niceties once you claim that you are Linux. It lumps all different variants of Linux into a single ball of wax and defines LINK_FUZZ_PROGRAMS Makefile macro, which is a bit unfortunate.
