Adhemerval Zanella Netto Feb. 24, 2016, 8:48 p.m. UTC 
This adds the Linux generic sysdep.h for all architectures.  The generic
sysdep.h defines basically two things:

  1. Define __NR_pread and __NR_write to __NR_pread64 and __NR_write64
     respectively for 64-bits architectures

  2. Define the __ALIGNMENT_ARG and __ALIGNMENT_COUNT macros to use
     for 64-bit argument passing on syscalls.

The p{read,write} definition is safe since for 64-bits the p{read,write}
will aliased to p{read,write}64.  The __ALIGNMENT_{ARG,COUNT} should be
safe if all the ABI correctly defines __ASSUME_ALIGNED_REGISTER_PAIRS.
This lead to the correct definition on the missing ABIs, mips64-n32
and x32.

Checked on x86_64, i386, aarch64, armhf, and ppc64le.
