Debian bullseye (testing at the moment, but seems close to release) has avr-libc 1:2.0.0+Atmel3.6.2-1.1 with some changes taken from the Atmel-distributed toolchain. In particular, the <avr/io.h> header for ATmega32A (avr/iom32a.h) now defines the FLASHEND constant as `0x7FFFU`, and that `U` suffix breaks the firmware size check code, because the shell arithmetic expansion that is used to calculate `MAX_SIZE` does not support those C-specific suffixes. As a workaround, add `-D__ASSEMBLER__` to the C preprocessor invocation that is used to expand those macros; in this case avr/iom32a.h defines `FLASHEND` without the `U` suffix, and everything works as it did before with older avr-libc versions. The exact same code is present in two places; they are both changed, even though the code in `tmk_core/avr.mk` is actually never used for ATmega32A (and the header for ATmega32U4 does not add that `U` suffix to `FLASHEND` for some reason).
