The section mismatch check relies on the relocation entries.
For REL, the addend value is implicit, so we need some code to compute
it. Currently, EM_386, EM_ARM, and EM_MIPS are supported. This commit
makes sure we covered all the cases.
I believe the other architectures use RELA, where the explicit r_addend
field exists.
