Link Error in SSL.c (WOLFSSL) undefined reference to `LowResTimer' link error

Clean Git project. Latest FreeRTOS and WolfSSL in the /lib directory.

Everything builds nicely.. with one error:

Oh man.. I'm never going to figure this out without help :(. This must relate to the PICO port... something not working right with the time function definition.

I'll take a look. It looks like something has changed in WolfSSL. The instant fix would be to wind back to the version of WolfSSL I used for the testing.

Yes, Use HEAD 12e285434 of wolfssl as a work-around for now. Thanks Jon for helping on this.
