[RFC] ubi-utils: improve compatibility with klibc

[Andrea Adami]

Hi,

I have put together a patchset allowing to compile the ubi utils
statically against klibc.

The patches are based on today's mtd-utils master, please have a preview here:

Please let me know if there is something to change before sending them
to the mailing list.

Thanks

Andrea
