Re: wget2 | `./configure --with-openssl=yes` fails with linker error (#595)

Looks like there is a clash. We use the gnulib modules `crypto/md5` etc. They 
set
```
LIB_CRYPTO = -lcrypto
```
used in `Makefile`.

We only want this if no other md5_* implementation exists.

Since recently we have to link with the whole gnulib library (see 
-Wl,--whole-archive in the linker command). I once created a patch for libtool 
to avoid this, but someone wanted to remove that so that `slibtool` can be used 
as a drop-in replcement for libtool. While `slibtool` is of no big interest to 
me, the opportunity to get rid of the libtool patch convinced me. Maybe that 
was a bad idea !?

We have to decide what to do:
- revert the changes and re-introduce the libtool patch
- drop the crypto modules from bootstrap.conf and don't provide hash algorithms 
in case no TLS or crypto library is available
- find another fix or work-around

While we tried to support all kinds of combinations in the past, we can 
possible simplify the build process and remove the --with-openssl code 
completely. And also remove the gnulib crypto / hash fallback modules from 
bootstrap.conf (second option in the list). WDYT ?
