It looks weird to me.

I think HOSTCC should be always "gcc".

In my understanding,  tools/env/fw_printenv is not a host program
but a one for the target embedded Linux.

Is there any reason that we don't fix tools/env/Makefile?

  $(obj)fw_printenv:      $(HOSTSRCS) $(HEADERS)
          $(HOSTCC) $(HOSTCFLAGS_NOPED) $(HOSTLDFLAGS) -o $@ $(HOSTSRCS)
          $(HOSTSTRIP) $@

to

  $(obj)fw_printenv:      $(HOSTSRCS) $(HEADERS)
          $(CC) $(HOSTCFLAGS_NOPED) $(HOSTLDFLAGS) -o $@ $(HOSTSRCS)
          $(STRIP) $@
