add pie
try this patch on top of:

I could reproduce the error, and this is now working for me (with the patch)

--- Comment #7 from R. Diez <rdiezmail-gcc at yahoo dot de> ---
I have been building cross-compiler toolchains for years with makefiles similar
to this one:
https://github.com/rdiez/JtagDue/blob/master/Toolchain/Makefile
I am trying to upgrade that makefile from GCC 10.2 to GCC 11.2, and I am
getting exactly the same problem that this bug describes.
I checked, and the fix linked from this bug is included in version 11.2 .
However, I have never used option "--enable-default-pie" in the past, and I was
able build cross-toolchains with many GCC versions without it for years.
The target is actually an embedded ARM Cortex-M3 microcontroller with fixed
memory addresses (a "bare metal" firmware without OS), so I guess that I do not
really need PIE. It may even cost some performance, if I understand what PIE
does.
I am guessing that bootstrapping a cross-compiler GCC is still broken with its
default PIE setting.
