The defaults for LibO are -Os for ia32 and -O2 for ia64 (and most other
gcc targets), IIRC we fell over and died with -Os back in the early days
of the x86_64 port so left it as -O2 since. Though likely the bug was
with us and not gcc and probably fixed along somewhere along the way
either way. Milage varies, now that I think about it I have
-Wp,-D_FORTIFY_SOURCE=2 -fstack-protector --param=ssp-buffer-size=4
additional flags in my env over the defaults.

Thoughts of debuginfo-style extraction of the sections to a compressed
external file and read them in on first-exception comes to mind :-)
