It appears that man2hlp above is built using an implicit builtin
rule, which for GNU make involves TARGET_ARCH for some reason.
I don't know where this is documented, but take a look:

    $ strings /usr/local/bin/gmake | grep TARGET_ARCH | grep CC
    $(CC) $(LDFLAGS) $(TARGET_ARCH)
    $(CC) $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c
    $(CC) $(CFLAGS) $(CPPFLAGS) $(LDFLAGS) $(TARGET_ARCH)

So your best bet is to add a rule for man2hlp to src/Makefile.in;
I'm attaching a patch agains the port to this effect; it seems
to work for me.
