You could wait a little, the pie patches could go into 0.9.24 (if Erik 
will do it), else take the patches I have sent to the uclibc list 
yesterday as tar.bz2 (not the separated ones sent earlier). The flipturn 
patch from gentoo is mostly included into uClibc cvs, the remaining part 
is attached.
I am enforcing NOELFRELOCS like behaviour in uClibc (I have it in 
PaX/grsec too like this), this could not be conformant to what you want 
to do. Really tested is the config with CTOR_DTOR enabled, the disabled 
version works on "Hello world" as ET_DYN, no other tests done.

The propolice implementation is what you've done with move-to-glibc, not 
the new ssp_x86 (waiting further more for an answer on the file you've 
sent me ;-( )

I have also sent all my specs/patches (not really sorted) for reference to 
solar (3.5MB compressed), he will probably put them online, all were 
tested with ET_DYN/propolice.
