 Yes, such as cross-compiling or embedded systems.  I think it's reasonable
 to make it a config option tho.

eh ?  rpaths are not needed when cross-compiling or for embedded.  they're 
needed only when people are installing into non-standard paths and can't be 
bothered to update their ld.so.conf mechanisms to include those paths.

can't be bothered is a rather loaded term.  Sometimes it is a bad
idea to force every application on a system to look for libraries
in a location needed by just one.  We should acknowledge that rpaths
are sometimes useful.

s/sometimes/rarely/

even then, it's trivial to keep this behavior -- set LDFLAGS yourself to your 
non-standard paths.  i don't think using rpath is a sane default.

 because people want to set custom linker flags.  `man ld` shows quite a large 
 number that can easily be applied such as extra hardening or optimization.

I ended up using the cflags in Configure for that.

This could perhaps be easier, but it is possible.

I think this misses the point, one can already just pass a table
entry on the command-line as a colon-separated target name.

The goal generally is not to create an entry from scratch but to
add some flags to entry maintained by the OpenSSL team which gets
updated from time to time by them to add various platform-specific
options.  It is for this that I wrote a script to synthesize an
ad-hoc target spec from the OpenSSL maintained table...

It would be convenient to specify additional ad-hoc prepend/append
strings for the various table fields on the Configure command-line
without writing a Configure TABLE parser, but at least that
approach works...

Yes, you're right, I was mis-using the thread.

But putting a config spec on the command line is, shall we say, awkward.  And 
adding the flag would help with code cleanup; does everyone need to see the 
various debug-levitte settings?  Or when we finally get rid of support for 
MSDOS, we can take that out, too.  Configure then becomes the practical 
definition for what is supported and not a dumping ground for anything that 
someone on the core team needs, or that someone was able to convince them to 
add.
