--- Comment #5 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
If CAN_USE_REGISTER_ASM_EBP is set to 1 it means the configure script was run
with a CFLAGS safe to use an optimized 6 argument syscall internally. If you
change the CFLAGS after the configure without change CAN_USE_REGISTER_ASM_EBP
it breaks the build as you see.
If you ran the configure in the way I suggested in the changeroot environment ,
does it work?
