Subject: Remove unneeded stubs for k_rem_pio2l.
X-Git-Tag: upstream/2.30~4331
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2bad840e9d4b3e714b4f20ad6b46a76e7be1d8fe;p=platform%2Fupstream%2Fglibc.git

Remove unneeded stubs for k_rem_pio2l.

This is only used for the float and double variants.

Instead, just add it to the type specific list of files,
and remove all stubs, and remove the declaration from
math_private.h.

I verified x86_64, i486, ia64, m68k, and ppc64 build.
