Portenta H7 Lite: Std lib atan2 causes a Undefined in Symbol Table

[mjs513]

While testing the DFRobot Lib for the BMM150 with the H7 Lite found that the use of atan2 in the library results in:

*** Booting Zephyr OS build v3.7.0-8126-g33bc8a018ecc ***
[00:00:00.573,000] <err> llext: Undefined symbol with no entry in symbol table a                      tan2, offset 2028, link section 12

while normally would just add the symbol to llext_exports.c begining to get concerned that it looks like to be complete would have add all the atan, acos etc std functions to the exports.c.

QUESTION: Is there an easier way to ensure that these are covered with out have to test each and every std function to ensure it will cause a error?

NOTE: have run the same example on the NANO but did not see this undefine appear?

NOTE1: The dfrobot bmm150 lib does not use the bosch API.

Going to close this as it was incorporated - just hope don't have to keep adding std functions
