Even if ubuntu provided a libressl package, we'd still need to build this
ourself, because we wish to statically link all the dependencies into the
plugin. This requires a relocatable (position-independant) static library, and
it would be very unlikely for Ubuntu to offer a libressl-pic package.
This appears to have caused performance regressions, which will need to be investigated.

...via moving it all to linux-only. Clang is picky about flags, and the osx
linker doesn't accept -z flags. Technically, this will likely break
clang-on-linux, but that's not a config that we run and I'll probably end up
fixing it later.
This makes us fully position independant and have a noexec stack. There's a
small chance that the former part of that can interfere with
gdb/corefiles/stackdumps, but we'll handle that if it becomes a problem.
