Hi,

I am doing my regular update in OpenADK and updated to glibc 2.35.
All toolchains are build fine except x86.

I am getting following error with binutils 2.37 and gcc 11.2:

Is it a known bug in binutils or glibc?

None we are aware of and we do build check on i686 constantly.  I just did a build
with gcc 11.2 and binutins 2.37 and I haven't see any issue.  How did you build
gcc and binutils?

Thanks for your response. It seems TARGET CFLAGS are not allowed to
be -Os or any machine specific optimizations for x86. Forcing -O2
did work.

I should work in fact, we have tracked multiple issues when building with -Os
over the releases [1][2][3][4][5][6][7][8].

The problem seems to the that now static-pie is enabled as default and it 
seems to be triggering this issue (with --disable-static-pie it does seem 
to work).

The localedef.o is built with -fpie, as expected, so I am not sure if the
issue is compiler that is emitting wrong relocations for -Os or binutils
that is not expecting it.  With -O2 gcc emits R_386_GOT32X which seems to
be fine.

H.J or Siddhesh, could you check on this?
