i don't think this description is accurate/relevant. looks like you're
trying to add a new search path to ldconfig/ld.so.cache so that people
can build libs w/-mavx2 turned on and then put them under a path e.g.
/lib64/avx2/ ?
you can't add arch-specific functionality to common code like this.
this patch will break all non-x86 arches.
i think you want to actually be updating these files:
sysdeps/i386/dl-procinfo.[ch]
sysdeps/x86_64/dl-procinfo.[ch]
