This from the min/max commit message makes me think we'll be fine:

> Note that clspv and spirv targets don't want to define these functions, so pre-processor macros replace calls to __clc_min with regular min, for example. This means they can use as much of the generic CLC source files
as possible, but where CLC functions would usually call out to an external __clc_min symbol, they call out to an external min symbol. Then they opt out of defining __clc_min itself in their CLC builtins library.
