do not strip /stand

This is a temporary workaround until the elftoolchain's version
of strip is fixed:

The previous (GNU) strip, when acting on a file with multiple links,
would modify the one and only file in place (which means creating
a new stripped copy, and then writing it back to the original).

The new version from elftoolchain creates the new file and then
unlinks the old one and renames the new.
With multiple hard links, the original remains alive.  In the /stand
directory, this ends up creating 80+ copies of the same file.
