[PATCH] [nolibc] Add RTSanitizerCommonNoLibc, a libc-free subset of sanitizer_common.

[Kostya Serebryany]

  I still don't like this ifdef clatter.
  Maybe we could create a few new files, like sanitizer_xxx_libcdep.cc, which and only which are allowed to depend on libc?
  Then your target will simply omit those files.

Please give us a chance to get rid of this. The change is under review now. 
Unfortunately it may still take some time since samsonov@ is on vacation. :(
