fix(tools): suppress GNU bin-utils warning about executable stack

Newer GNU bin-utils version 2.39 has started emitting a warning
about an executable stack region for Linux target build:

/usr/bin/ld: warning: x509_crt_bundle.S.o: missing .note.GNU-stack section implies executable stack

Fix the issue by adding appropriate "noexecute" attribute for stack
section.
