Changes in v2:

1. No need to include <nldbl-abi.h> in nldbl-compat.c.
2. Don't protect the __nldbl__IO_vfscanf compat symbol with

#if LONG_DOUBLE_COMPAT(libc, GLIBC_2_0)

--
__nldbl__IO_vfscanf is only needed in libnldbl_nonshared.a to define
_IO_vfscanf.  But _IO_vfscanfis a compat symbol and shouldn't be in
libnldbl_nonshared.a.  We can make __nldbl__IO_vfscanf a compat symbol
by

1. Remove _IO_vfscanf from libnldbl_nonshared.a.
2. Change libnldbl_nonshared.a to call __nldbl_vfscanf, instead of
__nldbl__IO_vfscanf.

H.J. Lu (2):
  Add scanf/vfscanf/vscanf tests of long double without <stdio.h>
  Make __nldbl__IO_vfscanf a compat symbol [BZ #31776]
