The error is:

00:04:49 ./include/linux/compiler-gcc.h:47:45: error:
‘__UNIQUE_ID___earlycon_hscif362’ causes a section type conflict with
‘banner’
00:04:49 47 | #define __UNIQUE_ID(prefix) __PASTE(__PASTE(__UNIQUE_ID_,
prefix), __COUNTER__)

This likely also happens on other architectures.
To reproduce a vanilla aarch64-linux-gnu stage1 cross compiler and any recent
Linux version is sufficient.
