Fails to compile with Arm GCC 10.3 and newer

[microbit-carlos]

This is because of the issue described in:

• (micro:bit V2 target) Does not compile with GCC 10.3 microbit-v2-samples#33
• https://community.arm.com/support-forums/f/compilers-and-libraries-forum/51596/lto-linker-error-with-gnu-arm-10-3-2021-07
• https://gcc.gnu.org/bugzilla/show_bug.cgi?id=103698
• https://sourceware.org/bugzilla/show_bug.cgi?id=26850

This was fixed in codal-core, so that dependency would need to be updated in this target:

• Fix for problems compiling on gcc 10.3.x+ codal-core#144

For now pxt-adafruit is fine because it uses pext/yotta:latest Docker image, which has arm-none-eabi-gcc v6.2.1 and this problem is only present on 10.3 and newer.
