[Patch 1/2] BaseTools: Update C tools top GNUMakefile with the clear dependency

[Liming Gao <liming.gao@intel.com>]

https://bugzilla.tianocore.org/show_bug.cgi?id=786
After GNUmakefile dependency is fixed up, it can make with -j N to enable
multiple thread build in base tools C source and save build time.

In my linux host machine, make -j 4 to compile BaseTools and save ~60% time.
