makefiles: use bash subshell

Avoid using  make's $(shell invocation since the eval order is
then somewhat different and use $$(  subshell.

This also fixes a problem when more then one symbol is found,
since target shell has been given separate word list
so the 'R' assignment would need "" around it.
