  make -C /home/ska/devel/dpdk EXTRA_CFLAGS="-g -O0"
RTE_KERNELDIR=/tmp/ubuntu-14.04/usr/src/linux-headers-3.13.0-51-generic
O=/home/ska/build/dpdk T=x86_64-default-linuxapp-gcc V=1

The config step works fine, but it fails on this step.

  /home/ska

is mounted on NFS, and

  /home/ska/build

is a symlink to

  /lhome/ska/build



It appears to work if I build outside the symlink, i.e.., build with
O=/lhome/ska/build/... instead.
