You could override the OE_QMAKE_CFLAGS env variable like this:
OE_QMAKE_CFLAGS="-O2 -pipe -feliminate-unused-debug-types" make

If you look in the Makefile generated by qmake you should see something
like:

CFLAGS = -pipe -pipe $(OE_QMAKE_CFLAGS) -O2 ....

This OE_QMAKE_CFLAGS variable is evaluated by make from the
environment. Also look at your environment-setup-* file from the
SDK, this is where all OE_QMAKE variables are sourced from.
