e0a53e2de3 Factor out R_GENERIC_ABSOLUTE
Combine:
 - R_AARCH64_ABS64
 - R_ARM_ABS32
 - R_X86_64_64
 - R_386_32

They do mostly the same thing as R_GENERIC_GLOB_DAT. They always have an
addend, though, and R_GENERIC_GLOB_DAT currently only has an addend on
RELA targets.

6d601458de Renumber arm64 TLS to match GNU values
The AArch64 ELF specification originally specified these relocations:

  R_AARCH64_TLS_DTPREL64          1028
  R_AARCH64_TLS_DTPMOD64          1029

However, the GNU toolchain implemented them as:

  R_AARCH64_TLS_DTPMOD64          1028
  R_AARCH64_TLS_DTPREL64          1029

The AArch64 ELF specification has been updated to replace the relocations
with R_AARCH64_TLS_IMPDEF1 and with R_AARCH64_TLS_IMPDEF2, where each
implementation can choose which interpretation it implements, but with a
suggestion to follow the GNU behavior.

Also: remove the 64 suffixes from the TLS relocations. The newest version
of the AArch64 ELF specification (version f) also omits the suffixes, as
do the glibc headers.

cbc80ba9d8 Switch the rest of our internal headers to #pragma once.
We've been using #pragma once for new internal files, but let's be more bold.

bcc4da9b75 Unify linker files under one license (BSD)
Historically we had part of the linker licensed under BSD and
another part under Apache 2 license. This commit makes all the
linker code licensed under BSD license.
