Linux: Make tcmalloc buildable on linux (does not enable it though).

Mostly changes to tcmalloc.gyp to get tcmalloc building for linux.
Supports the full google-perftools tool suite (heapchecker, heapprofiler, cpuprofiler).
Adds in a fix for malloc_hook.cc that is not upstream yet.  Forked malloc_hook.cc.
Forces linking in a symbol that is not used except by a static initializer which was getting stripped out, thereby getting heap profiler to work even when statically linked.
TODO: integrate with allocator_shim
TODO: support jemalloc
TODO: support debugallocation
