  -----------
  [lld-macho] Initial scaffolding for ARM32 support

This just parses the `-arch armv7` and emits the right header flags.
The rest will be slowly fleshed out in upcoming diffs.

  [lld-macho] Parse & emit the N_ARM_THUMB_DEF symbol flag

Eventually we'll use this flag to properly handle bl/blx
opcodes.
