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

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

* gen-idecode.c (print_idecode_issue_function_header): Use
lf_get_file_type() to issue an extern variable declaration in
case of header files.

# We default to building libraries optimised for size.  We use
# -minterlink-mips16 so that the non-MIPS16 libraries can still be
# linked against partly-MIPS16 code.  The -mcode-readable=pcrel option allows
# MIPS16 libraries to run on Harvard-style split I/D memories, so long
# as they have the D-to-I redirect for PC-relative loads.  -mno-gpopt
# has two purposes: it allows libraries to be used in situations where
# $gp != our _gp, and it allows them to be built with -G8 while
# retaining link compatibility with -G0 and -G4.
