Subject: [PATCH] build: Support running tests with memory sanitizers

When memory sanitizers are set, tests may fail because we are indirectly
LD_PRELOAD'ing (through umockdev). While we could ensure that sanitizer
libraries are loaded first, it's just something we don't care because we
don't want to test the launcher wrappers themselves.

So, let's just ignore the link order and live with it
