target/hexagon: Use explicit little-endian LD/ST API

[PATCH v3 3/3] configs/targets: Forbid Hexagon to use legacy native endianness API

Posted by Philippe Mathieu-Daudé 1 month, 2 weeks ago

The qemu-hexagon binary is buildable without a single use
of the legacy "native endian" API. Unset the transitional
TARGET_USE_LEGACY_NATIVE_ENDIAN_API definition to forbid
further uses of the legacy API.

Preliminary commits allowing this final change:

  - beb38fda0f0 target/hexagon: Replace MO_TE -> MO_LE
  - fdcb7483ae0 target/hexagon: Explode MO_TExx -> MO_TE | MO_xx
