>Description:
Building binutils-2.37 on Solaris 10 sparc64 gives me an error when trying to include and use include/plugin-api.h where it fails to detect the endian

With this patch it compiles, and is able to compile GCC8 using gas from binutils instead of the /usr/sfw/bin/gas version.
>How-To-Repeat:
Try to build binutils on Solaris 10 sparc
>Fix:
$NetBSD$
