first, i'm not a browser.
second, this is currently not supported. I'm not sure about the last
version that had this option (1.2.2.1, perhaps, not sure though).

With trunk, you may experiment with EXTRA_CFLAGS="-DPIE -pie"
EXTRA_LDFLAGS=-Wl,-pie but i'm pretty sure that this will need
additional hackery to drop flags that are disallowed there.
