Maybe your case is different with my case (but may be the same solving
ways).
After compare the 'flags', for my case, the root cause is:
"for allmodconfig, it will enable CPU_V6 which VEXPRESS doesn't support".
after disable CPU_V6 after allmodconfig, it can pass compiling:
("System type" -> "Multiple platform selection" -> "ARMv6 based platforms").
Welcome any additional suggestions or completions, if no additional
reply, I will try to send the related patch tomorrow. :-)
Thanks.
