OK, I will specify the underlying type explicitly.

This file tests the common part of the attribute section, i.e., attribute section header. However, since ELFAttributeParser is an abstract class, I need to use ARMAttributeParser or RISCVAttributeParser as the concrete object to run the test. I just pick ARMAttributeParser as the concrete object. This test is not used to test ARMAttributeParser.

You could refer to https://reviews.llvm.org/D74023#1911405. @MaskRay suggests to extract the common part out.
