[dpdk-dev] "cannot use T= with gcov target" when doing "makefile clean" with DPDK-2.1.0

[Montorsi, Francesco]

Hi all,

I found that after unzipping dpdk-2.1.0.tar.gz if I run:
       # make T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc    
config       
And then
    # make V=1 T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc    
clean

I get:

[...]
== 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= 
with gcov target".  Stop.
make[2]: *** [gcovclean] Error 2
make[1]: *** [clean] Error 2
make: *** [clean] Error 2

I guess the fix is:

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

Thanks,
