Module Name:    src
Committed By:   rin

Modified Files:
        src/sys/arch/amd64/include: param.h

Log Message:
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.
