[COMMITTED] libgloss: cris: Correct lcrt0.c for C23

With this, a combined build (gcc+newlib) for --target=cris-elf gets no
new regressions at r15-5326-gf242f79b8afe.  FWIW, there are lots of
warnings (156 for cris-elf with its three multilibs) for "old-style
function definition [-Wold-style-definition]" in the generic parts of
newlib.

Committed.

GCC commit r15-5326-gf242f79b8afe defaults to -std=gnu23, and in C23
void foo() means void foo(void), so old-style prototypes now get a
compilation error:

/x/libgloss/cris/lcrt0.c:107:1: error: conflicting types for 'start1';\
 have 'void(int,  char **, char **)'
  107 | start1 (int argc, char **argv, char **env)
      | ^~~~~~
/x/libgloss/cris/lcrt0.c:105:13: note: previous declaration of 'start1\
' with type 'void(void)'
  105 | static void start1 () __asm__ ("__start1") __attribute ((__use\
d__));

Fix by providing a full prototype.
