Comment (by Herbert Valerio Riedel <hvr@…>):

 Allow to compile OSMem.c when MEM_NORESERVE is not available

 On some OSes such as AIX `MEM_NORESERVE` is not available.

 Since this feature is only needed when the new two-step allocator (see
 #9706)
 is enabled we can simply turn this into a runtime error to avoid a larger
 refactoring of this already quite platform-sensitive code.
