After many tests and diffrent fixes this might be the one:

tail (and all coreutils programs) check for env variable _POSIX2_VERSION 
to determen their behaviour when dealing with parameters syntax etc.

_POSIX2_VERSION in glibc 2.3.2 is 199209
and in glibc 2.3.3 it is 200112

Solution to enable tail to use +/-<number> is to export 
_POSIX2_VERSION=199209 (or rather any value lower then 200112).

Ive already tested this with j2sdk and it seems to work, someone that 
use hostap-driver can test the attached patch.

We will have to take it one problem at a time now with the new glibc as 
standard.
