test: Fix some tests to run with musl

alexcrichton · alexcrichton · commit 01963a60c39e · 2015-04-24T15:14:19.000-07:00
There were a few test cases to fix:

* Dynamic libraries are not supported with MUSL right now, so all of those
  related test which force or require dylibs are ignored.
* Looks like the default stack for MUSL is smaller than glibc, so a few stack
  allocations in benchmarks were boxed up (shouldn't have a perf impact).
* Some small linkage tweaks here and there
* Out-of-stack detection does not currently work with MUSL
