uClibc-ng swapped the meaning of V=1 and V=2 in 2015 before
the 1.0.3 release.
Before that, V=2 printed the full commands while V=1 printed the
abbreviated versions.
This recipe was never updated to follow the change and we since
see brief build output only.
At the same time, convert V from an environment variable to
a make variable by adding to EXTRA_OEMAKE, so as to be in
line with how things are done in other recipes that use
kbuild.
