From: Ard Biesheuvel <ardb@xxxxxxxxxx>
Sections typically use leading dots in their names, and deviating from
this breaks some assumptions in the existing code, e.g., in strip_relocs
on x86, which filters out .rela.* and .rela__* sections.
[65] alloc_tags PROGBITS 0000000000000000 03a57958
0000000000026340 0000000000000000 WA 0 0 8
[66] .relaalloc_tags RELA 0000000000000000 08dbb868
0000000000044c40 0000000000000018 I 280 65 8
So use a leading dot for the alloc_tags sections.
