[U-Boot] [PATCH] Fixing `can't find crc32.c' error on non Linux platform

[Arnaud Lacombe <lacombar@gmail.com>]

This is a quick and dirty patch to fix the build on a NetBSD platform,
using Linux binary compatibility to run ELDK 4.2 toolchain for ARM.

It is not intended for any kind of inclusion, but might give some hints
about
what's wrong or allow people not to give up on this error. A couple of other
nits need to be sorted out to have a fully clean build on NetBSD (sha1.h
inclusion error, missing getline(3), etc.).

Build "succeeded" with GNU Make 3.81.
