While working on the changes requested by Adhemerval, I hit 2 other bugs:
1. getauxval() does not work well from a DSO dlopen'ed by a statically linked
executable.
2. errno from a DSO is lost in a statically linked executable (BZ #25335).
I've fixed the first issue, but I'm stuck with the second one.

The tests I implemented are failing because of these issues.
Would it be fine if I disabled the failing tests while we do not have a fix
for BZ #25335?
