gnu: gcc: Fix 'gcc-strmov-store-file-names.patch'.
Fixes <https://bugs.gnu.org/31708>.

Previously GCC would crash when encountering a 'static const' element
without an initializer, as in:

  #define _GNU_SOURCE
  #include <string.h>

  void foo (char *x)
  {
    static const char buf[12];
    memcpy (x, buf, 12);
  }

* gnu/packages/patches/gcc-strmov-store-file-names.patch: Return false
when DECL_INITIAL returns NULL_TREE.
