To unset the executable bit I ran following command:
for i in $(find -executable -type f); do chmod -x $i; done

One thing that I noticed is, once we initiate a kernel build some 
programs are compiled and removing their executable bit is not desirable.
Even after performing "make clean" some of those programs still persist and 
removing their executable bit fails any further attempt to build the kernel.

For instance, tools/objtool/objtool file. In my case I had a total of 19 
files remaining after performing make clean.
