Hi, Igor!

Thanks for the patch!
LGTM, except 4 comments about memory profiler parser below.

1. I suggest the following rewording ("I hope" is too personal :)):
s/I hope this file will have gone away/This file should go away/

2. @LUAJIT_BIN@ looks more convenient, doesn't it?

3. Unfortunately, your solution doesn't work for me:

| $ git log --oneline -n1
| 7badb7e (HEAD) build: preserve the original build system
| $ make -f Makefile.original  -j
| ==== Building LuaJIT 2.1.0-beta3 ====
| ...
| ==== Successfully built LuaJIT 2.1.0-beta3 ====

Side note: I suppose it is nothing bad to add corresponding lines about
tools building. At least it simplifies build debugging.
Feel free to ignore.

| $ tools/luajit-parse-memprof /tmp/memprof_memleak.bin; echo -e "\n"; cat tools/luajit-parse-memprof
| tools/luajit-parse-memprof: line 5: /home/burii/reviews/luajit/cmake/tools/memprof.lua: Permission denied

|
| LUA_PATH="/home/burii/reviews/luajit/cmake/tools/?.lua;;" \
|          /home/burii/reviews/luajit/cmake/tools/memprof.lua $@

This patch is working for me. But I am not bash|make guru :).

4. Please, create separate commit to tools-related changes.
Also, I suppose, it would be nice to add <tools/luajit-parse-memprof>
to <.gitignore> as far as it's generated. These lines may be confusing:

| $ git status
| HEAD detached at 7badb7e
| Untracked files:
|   (use "git add <file>..." to include in what will be committed)
|         tools/luajit-parse-memprof
