I missed most of the thread, so I'm not sure what you intend to do, but
if you want to compile stuff, why not use jam?

A shorter version would be "$(1:DBS)". But what are you trying to do?
Remove the grist? The grist is part of the target name and at least
MakeLocateDebug requires the correct target name.

Given that you call MakeLocateDebug for it, this apparently is supposed
to be a target. If so, its path needs to be bound/resolved at some
point. There's AddTargetVariableToScript which would do that, but would
also make the generated script depend on that target. So you might want
to pass it as a first parameter of the actions instead. If it is just a
temporary file produced by the script, I wouldn't declare any target
here, though, but simply choose an appropriate name and location (pass a
directory path, if necessary) in the script itself.

+ SEARCH on $(mainScript) = [ FDirName $(HAIKU_TOP) build scripts ] ;
+
+ Depends $(1) : $(mainScript) $(script) ;
+ KernelArgSizes1 $(1) : $(mainScript) $(script) ;
