[ARM,MIPS,M68K] Further kernel-features.h update for preadv/pwritev

["Joseph S. Myers" <joseph at codesourcery dot com>]

The libc copy of kernel-features.h now assumes preadv and pwritev are 
present in 2.6.30 on all architectures.  Thus the MIPS version no longer 
needs to define __ASSUME_PREADV and __ASSUME_PWRITEV, while the ARM and 
M68K versions need to undefine these macros explicitly.  I've committed 
the ARM and MIPS changes; OK to commit the M68K changes?
