No, but the error message seems to be different:

  HOSTCC  firmware/ihex2fw
/home/rafael/src/linux-next/firmware/ihex2fw.c:268: fatal error: opening dependency file firmware/.ihex2fw.d: Read-only file system
compilation terminated.

Removing the FORCE from line 117 of scripts/Makefile.host makes it work.

Of course, I still have to run "make ... firmware_install" locally on the
server.
