Refer to the commit a3c101a61348 ("examples: fix building on arm64") fix for arm32. crt0.S does not even build with CONFIG_API=y, CONFIG_EXAMPLES=y:
examples/api/crt0.S: Assembler messages: examples/api/crt0.S:32: Error: lo register required -- `ldr ip,=search_hint' examples/api/crt0.S:33: Error: lo register required -- `str sp,[ip]' examples/api/crt0.S:39: Error: lo register required -- `ldr ip,=syscall_ptr' examples/api/crt0.S:40: Error: lo register required -- `ldr pc,[ip]' make[2]: *** [scripts/Makefile.build:292：examples/api/crt0.o] Error 1
