Subject: mk: fix verbosity zero
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=684e6f4a78307796c45018c77908be4c96999e45;p=dpdk.git

mk: fix verbosity zero

Verbosity is considered enabled when $V is not empty.
It is a well spread shortcut in makefiles, see git grep '$(if $(*V'
So V=0 and V=1 are equivalent.
It is fixed by unsetting V when it is 0.

A side effect is to fix kernel module compilation verbosity
which is set to 0 when V is empty.
