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

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

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