scripts: llvm: Disable Picolibc FP exception and rounding tests
Browse files Browse the repository at this point in the history
LLVM compiler-rt does not currently support exceptions and rounding
modes for computations on the types that are emulated in software.

For more details, refer to the GitHub issue zephyrproject-rtos#838.

Revert this commit when this issue is fixed in the compiler-rt.
