Commit Message

Anton Johansson Nov. 21, 2024, 1:49 a.m. UTC
Adds a meson option for enabling/disabling helper-to-tcg along with a
CONFIG_* definition.

CONFIG_* will in future commits be used to conditionally include the
helper-to-tcg subproject, and to remove unneeded code/memory when
helper-to-tcg is not in use.

Current meson option is limited to Hexagon, as helper-to-tcg will be
included as a subproject from target/hexagon.  This will change in the
future if multiple frontends adopt helper-to-tcg.
