Yes, this is the right way. Profiling options belong to configuration
(which persist across make invocations) rather than to make invocation.
A seemingly elegant but not very robust approach is to have a special
target and use target-specific variables. The problem stems from the
multiple "paths" to build the same object file (but end up with
different code) which leads to inconsistent builds.
