Change subject: tests: Add lib/bootmem-test test case
......................................................................

Patch Set 2:

In v2 beside addressing review comments, I also fixed an issue with unit-test failing on Jenkins. It turns out, that newer (at least newer than the version I'm using on my machine) gcc versions are enabling PIE by default. This, combined with the fact that ASLR is applied for all position independent executables, makes my linker script with constant addresses for symbols useless.

In order to overcome above, I've added -no-pie option for bootmem-test compilation.
