x86/boot: Hide local labels in verify_cpu()
... from the final ELF image's symbol table as they're not
really needed there.
Before:
$ readelf -a vmlinux | grep verify_cpu
43: ffffffff810001a9 0 NOTYPE LOCAL DEFAULT 1 verify_cpu
45: ffffffff8100028f 0 NOTYPE LOCAL DEFAULT 1 verify_cpu_no_longmode
46: ffffffff810001de 0 NOTYPE LOCAL DEFAULT 1 verify_cpu_noamd
47: ffffffff8100022b 0 NOTYPE LOCAL DEFAULT 1 verify_cpu_check
48: ffffffff8100021c 0 NOTYPE LOCAL DEFAULT 1 verify_cpu_clear_xd
49: ffffffff81000263 0 NOTYPE LOCAL DEFAULT 1 verify_cpu_sse_test
50: ffffffff81000296 0 NOTYPE LOCAL DEFAULT 1 verify_cpu_sse_ok
After:
$ readelf -a vmlinux | grep verify_cpu
43: ffffffff810001a9 0 NOTYPE LOCAL DEFAULT 1 verify_cpu
No functionality change.
