+       Bump STACK_ALIGNBYTES to (16 - 1) to satisfy requirement by AMD64
+       System V ABI in kernel level. This is because
+       (1) for LLDB, we want to bypass libc/csu (and therefore manual stack
+            alignment in _start), and
+       (2) rtld in glibc >= 2.23 for Linux/x86_64 requires it.
+
+       Fix SEGV for Linux/x86_64 binaries with glibc >= 2.23, reported as
+       PR port-amd64/54052.
