Because we may have aliases, like __GI___strcoll_l in
/lib64/libc-2.10.2.so that appears in objdump as:
$ objdump --start-address=0x0000003715a86420 \
--stop-address=0x0000003715a872dc -dS /lib64/libc-2.10.2.so
0000003715a86420 <__strcoll_l>:
3715a86420: 55 push %rbp
3715a86421: 48 89 e5 mov %rsp,%rbp
3715a86424: 41 57 push %r15

So look for the address exactly at the start of the line instead
so that annotation can work for in these cases.
