    libctf: Add configure check for asprintf (for MinGW)

    This commit fixes a compilation warning when compiling libctf
    on MinGW:

        libctf/ctf-dump.c:118:8: warning: implicit declaration of function
        'asprintf'; did you mean 'vasprintf'? [-Wimplicit-function-declaration]

         if (asprintf (&bit, " %lx: [slice 0x%x:0x%x]",

    MinGW doesn't provide that function, so we depend on the one provided
    by libiberty. However, the declaration is guarded by HAVE_DECL_ASPRINTF,
    which we do not have in libctf's config.h.


        PR binutils/25155:
        * configure.ac: Add AC_CHECK_DECLS([asprintf]).
        * configure, config.h.in: Regenerate.
