Apply these two patches present upstream:
    
    Support-having-several-debuginfo-search-dirs-for-a-b.patch
    Add-a-fail-no-debug-info-to-abidiff.patch
    
    This is useful for some users that need to use abidiff in contexts
    where debuginfo for a given ELF binary is located under more than one
    root directory.
