[build] Avoid using multiple target patterns in pattern rules

Multiple target patterns in pattern rules are treated as grouped
targets regardless of the separator character.  Newer verions of make
will generate "warning: pattern recipe did not update peer target" to
warn that the rule was expected to update all of the (implicitly)
grouped targets.

Fix by splitting all multiple target pattern rules into single target
pattern rules.
