Nick Alcock 758f590744 libctf: add missing header in BFD ELF check
Without this, GCC warns:

In file included from conftest.c:36:
../../libctf/../bfd/elf-bfd.h: In function 'bfd_section_is_ctf':
../../libctf/../bfd/elf-bfd.h:3089:10: warning: implicit declaration of function 'strncmp' [-Wimplicit-function-declaration]
 3089 |   return strncmp (name, ".ctf", 4) == 0 && (name[4] == 0 || name[4] == '.');
      |          ^~~~~~~
../../libctf/../bfd/elf-bfd.h:3089:33: warning: 'strncmp' argument 3 type is 'int' where 'long unsigned int' is expected in a call to built-in function declared without prototype [-Wbuiltin-declaration-mismatch]
 3089 |   return strncmp (name, ".ctf", 4) == 0 && (name[4] == 0 || name[4] == '.');
      |                                 ^
<built-in>: note: built-in 'strncmp' declared here

These warnings do not currently throw off the result of the configure
check, but it's better to squash them anyway.

indexed, sorted symtypetab (and allow SYMFP to be NULL in this
case). Turn sorting off if this is a non-final link. Only delete

reported some.
