The static-declared string has previously been kept alive because of a use in __hyp_call_panic_vhe. Fix this in preparation for separating the source files between VHE and nVHE when the two users land in two different compilation units. The static variable otherwise gets dropped when compiling the nVHE source file, causing an undefined symbol linker error later.
