A testcase:
[hjl@gnu-17 tmp]$ cat x.S
.text
.globl _start
.type _start, @function
_start:
ret
.section ".note", "a"
#ifdef __LP64__
.p2align 3
#else
.p2align 2
#endif
.long 1f - 0f /* name length. */
.long 3f - 1f /* data length. */
.long 12345 /* note type. */
0:
.asciz "GNU" /* vendor name. */
1:
#ifdef __LP64__
.p2align 3
#else
.p2align 2
#endif
.long 0 /* pr_type. */
.long 5f - 4f /* pr_datasz. */
4:
.zero 0x10
5:
#ifdef __LP64__
.p2align 3
#else
.p2align 2
#endif

It is wrong to place note sections with 4 byte alignment in a NOTE segment
with 8 byte alignment.
