Samuel Holland authoredThe gcompat loader compiled as a static binary doesn't work on Linux since commit a4ff8e8620d3f4, failing with the error: ``` Uhuuh, elf segment at 0000000000400000 requested but the memory is mapped already ``` This is because the binary we are the ELF interpreter for 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 loaded at a different address. Signed-off-by:
