Zack Weinberg 35caceb145 Use PRINTF_LDBL_IS_DBL instead of __ldbl_is_dbl.
After all that prep work, nldbl-compat.c can now use PRINTF_LDBL_IS_DBL
instead of __no_long_double to control the behavior of printf-like
functions; this is the last thing we needed __no_long_double for, so it
can go away entirely.

Tested for powerpc and powerpc64le.
