Another thing to consider with regards to glibc assembly is that functions
using plain ENTRY as opposed to ENTRY_TOCLESS may incur extra overhead when
being called. For example when linking staticly, a call from pcrel code to a
function that uses r2 will never be direct to the local entry point. Instead
the call will go via a stub to the global entry point.
BTW, -Wl,-stats might be useful in tracking down these cases.
