Symbol name wrapper for the No-CRT bits.
In order to coexist in the same process as other CRTs, we need to decorate the symbols such that they don't conflict the ones in the other CRTs. The result of such conflicts / duplicate symbols can confuse the dynamic loader on unix like systems.
Define RT_WITHOUT_NOCRT_WRAPPERS to drop the wrapping. Define RT_WITHOUT_NOCRT_WRAPPER_ALIASES to drop the aliases to the wrapped names.
