How about something like:
-D) shift ; DEFINES="${1//_/ } ${DEFINES}"; shift ;;
mkconfig's interpreter is /bin/sh, so if you want to use the string replace 
bashism, you'll have to change it to /bin/bash.  or use the POSIX:
"#define ${1%%=*}\t${1#*=}\n${DEFINES}"
Do you have a non-bash version of my alternative (which handles multiple 
symbols rather than one symbol/value pair per -D)?  Or do we need to 
invoke sed to be portable?
Or can we just use bash? :-)
