    I get the following error from 'make modules_install' on my test boxes:
      HOSTCC  firmware/ihex2fw
    /home/rafael/src/linux-2.6/firmware/ihex2fw.c:268: fatal error: opening dependency file firmware/.ihex2fw.d: Read-only file system
    compilation terminated.
    make[3]: *** [firmware/ihex2fw] Error 1
    make[2]: *** [_modinst_post] Error 2
    make[1]: *** [sub-make] Error 2
    make: *** [all] Error 2
    where the configuration is that the kernel is compiled on a build box
    with 'make O=<destdir> -j5' and then <destdir> is mounted over NFS read-only by
    each test box (full path to this directory is the same on the build box and on
    the test boxes).  Then, I cd into <destdir>, run 'make modules_install' and get
    the error above.
    The issue turns out to be that we when we install firmware pick
    up the list of firmware blobs from firmware/Makefile.
    And this triggers the Makefile rules to update ihex2fw.
    There were two solutions for this issue:
    1) Move the list of firmware blobs to a separate file
    2) Avoid ihex2fw rebuild by moving it to scripts
    As I seriously beleive that the list of firmware blobs should be
    done in a fundamental different way solution 2) was selected.
