[patches] sh: Add ___fpscr_values to sysdeps/unix/sysv/linux/sh/sysdep.S.

[Nobuhiro Iwamatsu <iwamatsu@xxxxxxxxxxx>]

This solves __fpscr_valus in a link of the build in SH4. When it is resolved,
linker uses ld.so or libc.so.
When it was linked by ld-linux.so, GLIBC_PRIVATE is added to this.
But it was linked by libc.so, libc version is added to this.

With this patch, it is resolved by using __fpscr_valus of libc.so.
And this can solve a pattern to solve this by pattern and ld-linux.so
that __fpscr_valus
becomes unsolved.

This patch already was applied eglibc of Debian and Codesourcery.
