| 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. |
