FWIW I recompiled glibc now with debug info.
Now the linux boot goes further till this step :
...
NET: Registered protocol family 10
sit: IPv6 over IPv4 tunneling driver
NET: Registered protocol family 17
Key type dns_resolver registered
Initialized stdio console driver
Console initialized on /dev/tty0
console [tty0] enabled
console [tty0] enabled
bootconsole [earlycon0] disabled
bootconsole [earlycon0] disabled
Initializing software serial port version 1
console [mc-1] enabled
gdb gives :
tfoerste@t44 ~ $ pgrep linux | xargs -n1 -i{} sudo gdb
/home/tfoerste/devel/linux/linux {} -n -batch -ex 'bt'
warning: Cannot call inferior functions, Linux kernel PaX protection forbids
return to non-executable pages!
warning: Could not load shared library symbols for linux-gate.so.1.
Do you need "set solib-search-path" or "set sysroot"?
