I'm sorry, lately I added perf_buildid_config() but I didn't test by gcc-4.6.3

Why you use 'v' variable name ?
'v' variable name was used in set_buildid_dir(), too. But I send a patch renaming 'v' to 'home' because 'home' is more readable. 37194f4 ("perf config: Rename 'v' to 'home' in set_buildid_dir()") https://lkml.org/lkml/2016/3/27/98
IMHO, I like using 'dir' instead of 'v'.
Thanks, Taeung
