We need architecture (ISA) specific versions of the runtime and
the third-party packages built with it.  To this end, include
the $(CHPL_MAKE_TARGET_ARCH) component in the runtime library
path and the build/install path of each third-party runtime
package.
Factor lookup() into two versions: one recurses through module Uses and the other does not.

Pulling apart the two versions allowed significant simplification of the version that does
not recurse through uses.  Further code consolidation is possible, by making the helper
routines return (or merely populate) a vector of symbols and pushing the error-reporting
logic into the driver routine.
Simplify lookup helper by pushing symbol selection into the top-level lookup() routine.

This factors the common decision and error-reporting logic out of the duplicate routines.
Simply gathering up a vector of symbols also simplifies the overall logic.
Error reporting now lists all duplicate symbols before aborting. (TODO: we may need to
provide file/line or other context.)
Fix some coding errors.

* alreadyVisited is now a reference, so use "." member access in place of "->".

* Reworked logic of the
    if (fn & fn->_this)
clause to obtain previous behavior and remove redundant else clause.

Fix problems in our file timestamp adjustments.

We were still seeing problems with attempts to rebuild things, due to
losing the file timestamp information when we put the untarred sources
into the repository and get them back out.  This change seems (cross
fingers) to solve those problems.

While here, I removed the sleep commands, because I don't think they're
actually needed.

Ignore noinit for the record type regexp, it contains a field which is a c
pointer and assumes it needs to clean up that pointer during assignment when, if
noinit is used, that field would be null and thus not capable of being cleaned
up.
