[PATCH] Fix generic expm1l for large parameters.

[David Miller]

This simply mirrors the fix made to the i386 and x86_64 versions, and
this subsequently cures the last naggling glibc test case failures on
sparc32 and sparc64.

Any objections?

	* sysdeps/ieee754/ldbl-128/s_expm1l.c (__expm1l): Use expl for
	large parameters.
