Ferruh Yigit 65d3ba3264 eal: fix build with glibc < 2.12 ...

build error:
  CC rte_cycles.o
  cc1: warnings being treated as errors
  ...dpdk/lib/librte_eal/common/arch/x86/rte_cycles.c: In function
  ‘rdmsr’:
  ...dpdk/lib/librte_eal/common/arch/x86/rte_cycles.c:67:2: error:
  implicit declaration of function ‘pread’
  ...dpdk/lib/librte_eal/common/arch/x86/rte_cycles.c:67:2: error:
  nested extern declaration of ‘pread’

from pread man page:
pread(), pwrite():
   _XOPEN_SOURCE >= 500
   || /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L

For glibc < 2.12 _XOPEN_SOURCE >= 500 is required.

Adding _GNU_SOURCE define to the file which implies _XOPEN_SOURCE=700
