how to turn off PIE on Fedora?

[Per Bothner]

Can any Red Hat engineers shed light on this:

Data seems to move around unpredictably under Fedora Core.
I.e. I run cc1 under gdb to a breakpoint or error, and note
the memory address of some variable.  I then re-run cc1 with
no changes, and the variable has jumped to a different address.
This complicates debugging, and specifically setting conditional
breakpoints.

This presumably is because of PIE "position independent
executables", which is supoosed to increase security.  Fine -
but how can I turn it off for development builds?

PIE also breaks PCH, and hence running the gcc testsuite.
