This patch: fafd3ec9

 assumes that tools must build from
the main makefile folder.
This assumption leads to the error when somebody wants to
build a tool from the tool's folder.
Hence changes are done to provide the default binary name
in the tool's makefile.

Currently, the tool's makefile override the tool's binary name
which is already been defined in the main makefile.
Hence fix is provided so that the tool's makefile get the tool's
binary name from the main makefile instead of overriding it.
