libctf: compilation failure on MinGW due to missing errno values

Browse Source 
This commit fixes a compilation failure in a couple of libctf files
due to the use of EOVERFLOW and ENOTSUP, which are not defined
when compiling on MinGW.

libctf/ChangeLog:

	PR binutils/25155:
	* ctf-create.c (EOVERFLOW): If not defined by system header,
	redirect to ERANGE as a poor man's substitute.
	* ctf-subr.c (ENOTSUP): If not defined, use ENOSYS instead.

(cherry picked from commit 50500ecfefd6acc4c7f6c2a95bc0ae1945103220)
