The point of at least some of these uses of pwd is to get the physical
directory with symlinks resolved, not the shell's notion of the directory
that may involve symlinks. It would need to be pwd -P, if that's
sufficiently portable. (Really io/ftwtest-sh should be running pwd on the
test host not the build system, but that would require a new addition to
the set of test-wrapper makefile variables.)
