Fails to build when `mbed-trace.enable=1` and TRACE_LEVEL_DEBUG

[froeba]

Steps:

• mbed target = K64F
• mbed toolchain = GCC_ARM
• Clone and setup dev certificate and update certificate
• Change mbed-trace.enable from null to 1
• Change macro to "MBED_TRACE_MAX_LEVEL=TRACE_LEVEL_DEBUG",
• run mbed compile Expect: successful build

Actual result: Build fails at final step

Hi @bertfroeba, unfortunately the code just cannot fit there anymore on the target.

release profile/different compiler might help here, but these are the limitations with all the boards.

Closing. Generally it cannot be expected that all targets have enough flash to enable all features by default.
