config: make M5_PATH a real search path
Review Request #2528 - Created Nov. 23, 2014 and submitted
Changeset 10559:ad009eb6579b --------------------------- config: make M5_PATH a real search path Although you can put a list of colon-separated directory names in M5_PATH, the current code just takes the first one that exists and assumes all files must live there. This change makes the code search the specified list of directories for each individual binary or disk image that's requested. The main motivation is that the x86/Alpha binaries and the ARM binaries are in separate downloads, and thus naturally end up in separate directories. With this change, you can have M5_PATH point to those two directories, then run any FS regression test without changing M5_PATH. Currently, you either have to merge the two download directories or change M5_PATH (or do something else I haven't figured out).

seems fine, but i've never been thrilled about the use of a builtin function file() as an identifier/parameter in this code
