Debian gcc's is nowdays compiled with --enable-default-pie which means it d=
oes
-fPIE by default. This breaks atleast x86-64 compiles.
This is the third attempt to fix it, this time by using runtime detection of
the -fno-PIE compiler switch (it was introduced in gcc 3.4, min required gc=
c is
currently 3.2) so it can be backported to the stable kernels.
As noted by Al this won't fix `git bisect' of stable kernels prio this comm=
it.
However using always a wrapper around gcc which adds -fno-PIE is not sollut=
ion
I want to rely in future.
