[U-Boot-Users] [PATCH] Use `ln -sf` rather than `rm -f && ln -s`

[Mike Frysinger <vapier@gentoo.org>]

odd ... git-send-email ate the explanatory text ...

The -f option to `ln` should give the same behavior as the -f option to the
`rm` command.  It is better to do this in one shot so as to avoid race
conditions when building in parallel.  I build on a quad G5 and without this
change, it isn't uncommon for the build to fail when using -j8 due to this
small window where the files don't actually exist.
