The definition originates in
https://nxr.netbsd.org/xref/src/sys/arch/arm/include/sysarch.h#58
I've added the prefix SYSARCH to avoid any naming conflict concerns.
It looked a bit like an error on a first impression :-)
* config/arm/netbsd-elf.h (SYSARCH_ARM_SYNC_ICACHE): New definition.
(CLEAR_INSN_CACHE) Use it.
