[PHP-DEV] 7.1.8 RC1: compiler warnings

Fri, 21 Jul 2017 05:00:07 -0700

i don't think it's really helpful opening everytime new bugreports and so i changed our build to use "make --quiet" - collected output at the bottom and flags/configure at begin to provide some context 

they are not at a really high count and probably worse to get silenced
first "prof-gen" and the "prof-use" which enables implicit optimizations where i am not sure if it makes a difference
