Several commits to the ldbl-128ibm-compat directory added new files
where the URL in the copyright notice pointed to an http, rather than to
an https, address. This happened because I copied the notices before
commit ID 5a82c74822. This trivial patch fixes this issue.
Similarly to the functions from the *printf family, this patch adds
implementations for __obstack_*printf* functions that set the
'mode_flags' parameter to PRINTF_LDBL_USES_FLOAT128, before making calls
to __vfprintf_internal (indirectly through __obstack_vprintf_internal).
Tested for powerpc64le.
