builds: don't pass -silent to qt when building in debug mode

This means we'll get build output like this when building with DEBUG=1:

g++ -c -pipe -ffunction-sections -O2 -fPIC -std=c++11 -fno-exceptions <lots more> ../../corelib/kernel/qcoreapplication.cpp

rather than just:

compiling ../../corelib/kernel/qcoreapplication.cpp
