This is because lld 17 defaults to errors when undefined symbols are
referenced in linker version scripts. The problem is due to the Makefile
JvmMapfile.gmk, which generates a linker version script. It uses "nm
--defined-only" to dump symbols in object files, but this also includes
local (hidden) symbols. Add "--extern-only" to make it only dump global
symbols.
