[PATCH v2 0/2] elf: Handle ld.so with LOAD segment gaps in _dl_find_object (bug 31943)

[Florian Weimer]

This is the minimal version of the fix, without any page size
optimizations.

While extending the test case, I realized the original fix did not
actually work because of the missing l_find_object_processed update,
which is included here.

Tested on powerpc64le-linux-gnu.

Version 2 incorporates some minor test fixes.
