Hi all,

I found that after unzipping dpdk-2.1.0.tar.gz if I run:
       # make T=3Dx86_64-native-linuxapp-gcc O=3Dx86_64-native-linuxapp-gcc=
    config=09
And then
    # make V=3D1 T=3Dx86_64-native-linuxapp-gcc O=3Dx86_64-native-linuxapp-=
gcc    clean

I get:

[...]
=3D=3D Clean app/proc_info
make -f /home/fmontorsi/Downloads/dpdk-2.1.0/GNUmakefile gcovclean
make -f /home/fmontorsi/Downloads/dpdk-2.1.0/mk/rte.sdkgcov.mk gcovclean
/home/fmontorsi/Downloads/dpdk-2.1.0/mk/rte.sdkgcov.mk:34: *** "Cannot use =
T=3D with gcov target".  Stop.
make[2]: *** [gcovclean] Error 2
make[1]: *** [clean] Error 2
make: *** [clean] Error 2
=09
I guess the fix is:

Let me know if the patch above is wrong or I should do something else to co=
ntribute it to the project in the right way.

Thanks,
