revamp preparation of command line for qmake calls in makefiles

instead of re-assembling a list from the variables, take the original
command line minus some explicitly stripped out options. this is way
less code and poses no synchronization problem between the two parts.

as a "side effect", variables obtained from $QMAKEFLAGS won't multiply
with each makefile nesting level, as the generated command line won't
replicate data obtained from the environment.
