It seems, it exists the ECos way for that (to make it with own CDL
rule), but Unix way is just to filter that

I did prepare same NOOPTIM.ECM using 'sed' and then import it

ecosconfig new target

sed -ne '/CYGBLD_GLOBAL_CFLAGS {/,/^}/p' ecos.ecc |
sed  -e '/# user_value/s/# //;s/-g -O2/-g -O0/;/#/d;/^$/d' >NOOPTIM.ECM

ecosconfig import NOOPTIM.ECM
ecosconfig resolve
