* sysdeps/unix/sysv/linux/sparc/sparc32/nldbl-abi.h: New file.

	* sysdeps/ieee754/ldbl-opt/math_ldbl_opt.h: #include <nldbl-abi.h>
	to define LONG_DOUBLE_COMPAT_VERSION.  Use that in place of
	NLDBL_VERSION.
	* sysdeps/ieee754/ldbl-opt/Versions: Include <nldbl-abi.h>.
	* sysdeps/unix/sysv/linux/sparc/sparc32/Versions: Revert last change.
