[PATCH] sparcv9: Restore fdiml@GLIBC_2.1 [Was Re: [PATCH 3/3] sparc32/sparcv9: add a VIS3 version of fdim]

[Paul E. Murphy]

Hi Aurelien,

[Sorry for the duplicate, I forgot the CC to libc-alpha]

I tested using the F22 cross-compiler on x86-64, and verified
the symbol is once again exported.

It turns out most other architectures don't have quite as
convoluted Implies as ppc64.

Likewise, doing "#include_next <s_fdim.c>" gave me a
compiler error.

I'll commit the following if it is ok.

---8<---
Use s_fdim.c from sysdeps/ieee754/ldbl-opt/ instead of
math/ to ensure a compat symbol for fdiml is created.

	[BZ #20517]
	* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_fdim.c:
	Include ldbl-opt/s_fdim.c to ensure fdiml@GLIBC_2.1 is
	exported.
