[dpdk-dev] [PATCH] mk: Fix examples install

[Christian Ehrhardt]

Forgot to mention, an easy way to test-trigger this e.g. on the dpdk 2.2
tarball.

make clean; make config T=x86_64-native-linuxapp-gcc && && make -j && make
V=1 DESTDIR=Test install-doc

In this example the install-doc fails with this:
[...]
Build complete [x86_64-native-linuxapp-gcc]
make -f /home/ubuntu/dpdk-2.2.0/mk/rte.sdkinstall.mk install-doc
cp -a /home/ubuntu/dpdk-2.2.0/examples Test/usr/local/share/dpdk
cp: cannot create directory ‘Test/usr/local/share/dpdk’: No such file or
directory
/home/ubuntu/dpdk-2.2.0/mk/rte.sdkinstall.mk:160: recipe for target
'install-doc' failed
make[1]: *** [install-doc] Error 1
/home/ubuntu/dpdk-2.2.0/mk/rte.sdkroot.mk:101: recipe for target
'install-doc' failed
make: *** [install-doc] Error 2
