make include/linux/version.h cross compiled

[tchiwam]

Hello,

	I have had some troubles trying to compile linux from a platform
that is not using gnu expr (sh-utils) the term "lenght" is not the least
common denominator. If I am not wrong my little patch makes this easier to
cross compiler from foreign arch and should not affect native compiles...

	I leave it to you guys to decide what to do with this. Thank you
for your work.
