Hello everyone,

I previously sent a patch to fix the issue I got with "getconf"
which may not available in some embedded systems [1][2].

Cyril proposed to implement a tst_getconf to implement subset of
variables [3]. Based on his remark, I implemented it and I use "sysconf"
function that allows to retrieve configuration's variables at runtime[4].
Thanks to that, we are not depending anymore on a binary and we can retrieve
variables such as PAGESIZE or _SC_NPROCESSORS_ONLN.

The first patch adds this new library and the second patch replaces
"getconf" by "tst_getconf" in all the tests.

If you have any review/remark, do not hesitate!
Thank you in advance,
Mylène
