Newlib built using `-Os` causes things like `memcpy` to be very slow on the RP2350 because it uses byte-wise operations. On the RP2040 this doesn't matter because there is a ROM routine we use instead of the library, but on the Pico 2 it's almost 10x slower than the optimal method. Update GCC to 12.4 Update Newlib to 4.4.0 Move to -O2 library compilation New toolchain looks to add ~10K to RP2350 flash usage (less on the RP2040).
