For modules that depend on the reallocarray module, like ialloc, xalloc, and safe-alloc, it was not possible to skip importing the reallocarray module as they all contained at least one function that called reallocarray() and would cause build failure if the host system didn't declare it. This upstreamable patch adds macros that toggle whether to define functions that depend on reallocarray() based on whether the reallocarray module is being imported.
