+ Abstract:
+ This fixes a problem on MUSL where the initial stack size reported by the
+ pthread_attr_getstack is about 128kB, but this limit is not fixed and
+ the stack can grow dynamically. The problem is that it makes the
+ functions ReflectionInvocation::[Try]EnsureSufficientExecutionStack
+ to fail for real life scenarios like e.g. compilation of corefx.
+ Since there is no real fixed limit for the stack, the code below
+ ensures moving the stack limit to a value that makes reasonable
