I have reproduced the problem with rootfs.stage1.tar.xz (the release) as a base. It is failing at same point so it is not related to the use of rootfs.stage0.tar.xz as a base

Just as a curiosity, it has failed also when trying to create stage0 with optimizations for odroidxu4 when I ran DEVICE_OPTIMIZATION=odroidxu4 make bootstrap

I think the problem is related to CFLAGS provided by odroidxu4 optimization which appears incompatible with glibc for now.

After trying different workarounds in Pkgifle and different CFLAGS the same error still appears.
It should be noted, that I am compiling glibc with the gcc version 10.4.0 (CRUX-ARM 3.6) that I have on my odroidxu4 host.
What I am going to try is to reinstall the odroidxu4 with release 3.7-rc4 and try with the gcc 12 that it has, since the error could be due to "a change in gcc when they reorder assembler architecture directives" https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101723

Tested "export ASFLAGS" build optimization for cubieboard and cubieboard2.
We will add the export on the overlay for all devices.

@pitill0 Do you think we can close this issue after adding ASFLAGS to glibc ports? +1 here

Yes. It seems to solve the optimización problem
