This fixes a long standing weird issue of doing non-docker builds of FDB
can hit problems of $CC not being defined in link-wrapper.sh. It turns
out that this is because the official docker image defines CC in the
environment, and no one else does that.
Instead, we can just force Make to propagate its setting of CC into the
environment, thus requiring no extra configuration to be able to do a
build.
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.
