[Bug 1088677] [NEW] rtld: limit self loading check to normal mode only

[Rodrigo Belem]

Public bug reported:

Commit glibc-2.14~10 disallowed rtld self loading to avoid a segfault

that used to happen when rtld was loading itself in normal mode.

Unfortunately, that commit disallowed all modes of self loading,

including those that used to work before.  This change limits the check

for self loading to normal mode only, so that instruments like ldd could

handle rtld properly.
