OK, I was able to reproduce the error. Here it goes (all done from the
Buildroot top dir, path:  /home/ymorin/dev/buildroot/buildroot ):

Attempt #1:

    $ mkdir ../O
    $ cd ../O
    $ make -C ../buildroot O=$(pwd) defconfig
    $ make uclibc
    # Success!

Attempt #2:

    $ mkdir test/O
    $ make O=test/O defconfig
    $ make O=test/O uclibc
    # Bummer, failure.

So, it all happens because of the origin of $(O), it seems.

Guido and I have been discussing that on IRC, and I'm testing to
"unexport O" in the path where umask is wrong.

Regards,
Yann E. MORIN.
