Mirko Vogt ad11341e9e Do not use $(V) - force AM_V=1
Projects using silent-rules might otherwise fail to compile.

This is due to the following resulting Makefile code:

AM_V_P = $(am__v_P_$(V))
am__v_P_ = $(am__v_P_$(AM_DEFAULT_VERBOSITY))
am__v_P_0 = false
am__v_P_1 = :

Automake directly uses $(V) for variable name expansion
which fails if $(V) is set to sth. else other than '0' or '1'.

This patch forces automake to not take $(V) into account
but to always use the default config for verbosity.

A better approach would be to actually take $(V) into account,
however not just pass it through (AM_V='$(V)') but
set AM_V to 0 if $V=0 / unset and to 1 otherwise.

This plan however is foiled due to my frustration about
automake as well as my lack of m4 skills.
