Subject: For those wanting to build for several platforms with the same source
X-Git-Tag: OpenSSL_0_9_6e~26^2~3
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=c2aa4f2081e18999ccf2ca466ac69afe67c2b291;p=oweals%2Fopenssl.git

For those wanting to build for several platforms with the same source
directory, making a separate directory tree with lots of symbolic links
seems to be the solution.  Unfortunatelt, Configure doesn't take appropriate
steps to support this solution (as in removing a file that's going to be
rewritten).  This change corrects that situation.  Now I just have to
find all other places where there's lack of support for this.
