Description
The GNU and Solaris linkers have a flag to disallow unresolved external symbols when linking a shared object:
"-z defs"
The JVM is not supposed to have any unresolved external symbols, so if someone accidentaly introduces one the build will complete but attempting to start the JVM by dlopen:ing it in the launcher the loader will fail.
Suggested fix is to append "-Wl,-z,defs" to LFLAGS_VM
