sim/igen: Fix linker error with -fno-common

Browse Source 
GCC 10 enables -fno-common by default.  This resulted in multiple
definition linker errors since a global variable was declared and
defined in a header file:

  ld: libsim.a(idecode.o):sim/v850/idecode.h:71: multiple definition of
  `idecode_issue'; libsim.a(irun.o):sim/v850/idecode.h:71: first defined
  here

  ld: libsim.a(engine.o):sim/v850/idecode.h:71: multiple definition of
  `idecode_issue'; libsim.a(irun.o):sim/v850/idecode.h:71: first defined
  here

  ld: libsim.a(support.o):sim/v850/idecode.h:71: multiple definition of
  `idecode_issue'; libsim.a(irun.o):sim/v850/idecode.h:71: first defined
  here

  ld: libsim.a(semantics.o):sim/v850/idecode.h:71: multiple definition
  of `idecode_issue'; libsim.a(irun.o):sim/v850/idecode.h:71: first
  defined here
