Sdk7.1 was 2010 timeframe and did not support C99 and in particular did not support those functions.

fmin and fmax did not exist for c89 so with that target they should not be generated, at least not unless it provides its own definition. Might be a bug in the code generation phase. Not really a Sdk7.1 bug because with that target no call to them should have been created.
In the meantime you will probably need to supply your own definition for them. Should be very straightforward unless you need to handle nan
