100% sure.

That is really the ONLY (and likely) reason I can see for this.
I agree, and that's the reason why I was writing the email in the first
place because it does not make any sense to me.
I can also confirm that the x86_64 machine does the compiling as well (it
shows in distccd.log) - Could the CFLAGS/CXXFLAGS have anything to do with
 -march=armv8-a+crc+simd -mcpu=cortex-a53 -mfpu=neon-fp-armv8 -Ofast
-frename-registers -falign-functions=16 is used.
