xtensa: ldso: make GOT protection adjustment conditional
Xtensa PERFORM_BOOTSTRAP_GOT macro uses mprotect to make bits of GOT writable, but noMMU linux kernel returns ENOSYS to mprotect syscalls, and syscall wrapper tries to update errno with the error code. This happens well before the relocations are done and results in writes to unrelated locations, memory corruption or protection violations. Only define PERFORM_BOOTSTRAP_GOT when building xtensa configuration with MMU support. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
