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]", ^~~~~~~~ vasprintf 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. libctf/ChangeLog: PR binutils/25155: * configure.ac: Add AC_CHECK_DECLS([asprintf]). * configure, config.h.in: Regenerate.
