Following those instructions fixes this build error for me.
Can ktr/lkp do that?
Otherwise just ignore this ERROR.
Set CONFIG_EXPERT=y
and CONFIG_LD_HEAD_STUB_CATCH=y.
However, after doing that, I get these messages:
INFO: Uncompressed kernel (size 0x30ef664) overlaps the address of the wrapper(0x400000)
INFO: Fixing the link_address of wrapper to (0x3100000)
