//! Targets the ARMv4T architecture, with `a32` code by default.
//!
//! Primarily of use for the GBA, but usable with other devices too.
//!
//! Please ping @Lokathor if changes are needed.
//!
//! **Important:** This target profile **does not** specify a linker script. You
//! just get the default link script when you build a binary for this target.
//! The default link script is very likely wrong, so you should use
//! `-Clink-arg=-Tmy_script.ld` to override that with a correct linker script.
