[PATCH] Fix known_glibc_specials comparison

Hi Tulio,

Err, I think, based upon your code you mean that path should be "usr/lib/libfoo.so"
instead of just "libfoo.so".  (ie without the leading forward slash - there is
already code at the start of is_special_glibc_binary that handles absolute paths).

> In those cases, we need to remove all the directories before calling

I am reluctant to accept this change because it would treat, eg "build/getent"
as a glibc binary when it almost certainly should not.  I would prefer it if
only a known set of path prefixes were allowed.

Instead, would you mind trying out the attached alternative patch and let me
know if it solves the problem that you were investigating ?

Cheers
   Nick
