Noticing stack smashing issue during HWP exection.

libekb-p10 is built by default with -fstack-protector-strong flag due to this any buffer access or invalid size will result in stack smashing issue.

At present disabling stack protection using recipe level patch, but we need to revisit after fixing the compiler warnings during the ekb hardware procedure build.

This is the code change done which we need to revert

-bash-4.2$ diff Makefile.am Makefile.am.mod

< 		-fpermissive -fno-exceptions -fno-rtti \
---
> 		-fpermissive -fno-exceptions -fno-stack-protector -fno-rtti \
