Merge branch 'patch-4' into 'master'
New kernel compatibility; obstack; pthread_getname_np
The gcompat loader compiled as a static binary doesn't work on Linux since [a4ff8e8620d3f4](https://github.com/torvalds/linux/commit/a4ff8e8620d3f4f50ac4b41e8067b7d395056843), failing with an error like:
```
[349055.473655] 13325 (cmake): Uhuuh, elf segment at 0000000000400000 requested but the memory is mapped already
```
This is because the actual binary we want to run is also loaded at 0x400000. While it's actually okay to overlap the binary, since we're going to call `execve` again, the kernel doesn't allow the overlap anymore. Fix that by compiling the loader as static PIE, so it can be put at a different address.
Also add `pthread_getname_np` and the option to link `obstack`.
