Trying to build 218 but I am getting undefined reference error. The
source code of bus-error.c mentions that gcc magically maps these
variables but not for me.

What is doing the mapping? __attribute__ ((__section__("BUS_ERROR_MAP"))) ?

Could it be that mentioned "gcc magic" is not supported on cross compiling?

Also, why do we need to use elf section instead of iterating over
bus_standard_errors[]?
