When linking statically, the order of libraries on the linker command
line is important, and sconeserver got it wrong.
Also, sconeserver does not use pkg-config, so it misses the private
libs of -lcrypto, which is linking with -lz.
Fix that:
- add a patch to configure.in to fix the order of libraries;
- forcibly pass -lz when linking statically with openssl.
Note: we were already reconfiguring sconeserver, because it comes from
the github repository.
Fixes:

configure: re-order SSL libs when linking
|
|
|
|
When doing static builds, the ordering of libs is important, as the
|
|
linker does not back-pedal to previous libraries specified on the
|
|
command line to find missing symbols, and only searches for those
|
|
missing symbols in the following libs.
|
|
|
|
Thus, as -lssl needs symbols from -lcrypto, it needs to come before
|
|
-lcrypto.
|
|
|
|
And globally, we do *not* append new libraries, we prepend them.
