Yeah, I got the same error, along with a bunch of warnings earlier in the build about how 32-bit builds are deprecated on recent macOS versions. And then when it goes to link, it can't find the 32-bit symbols for functions like sqrt() and `printf()`. Hacky workaround: comment out the "CONFIG_M32=y" line in the makefile. This will disable building the 32-bit versions of some tools. ("Edit the makefile" is, according to the docs, the canonical way to customize your build settings.) And I don't think there's any real shortcut for dealing with compiler error messages. You've just got to learn what they mean and what sort of thing tends to cause them.
