WITH_LTO no longer gets applied when being called from Mk/Uses/cargo.mk, it
does however work if you define it in a port.

Example:

make -V CARGO_ENV
CARGO_HOME=3D/usr/ports/audio/ebur128/work/cargo-home  CARGO_BUILD_JOBS=3D6=
=20
CARGO_BUILD_TARGET=3Dx86_64-unknown-freebsd=20
CARGO_TARGET_DIR=3D/usr/ports/audio/ebur128/work/target=20
CARGO_TARGET_X86_64_UNKNOWN_FREEBSD_LINKER=3D"cc"  RUSTC=3D/usr/local/bin/r=
ustc=20
RUSTDOC=3D/usr/local/bin/rustdoc  RUSTFLAGS=3D"-C target-cpu=3Dtigerlake -C
link-arg=3D-fstack-protector-strong" RUST_BACKTRACE=3D1

Adding WITH_LTO=3Dyes to port Makefile:

CARGO_HOME=3D/usr/ports/audio/ebur128/work/cargo-home  CARGO_BUILD_JOBS=3D6=
=20
CARGO_BUILD_TARGET=3Dx86_64-unknown-freebsd=20
CARGO_TARGET_DIR=3D/usr/ports/audio/ebur128/work/target=20
CARGO_TARGET_X86_64_UNKNOWN_FREEBSD_LINKER=3D"cc"  RUSTC=3D/usr/local/bin/r=
ustc=20
RUSTDOC=3D/usr/local/bin/rustdoc  RUSTFLAGS=3D"-C target-cpu=3Dtigerlake -C
link-arg=3D-fstack-protector-strong" RUST_BACKTRACE=3D1
CARGO_PROFILE_RELEASE_LTO=3D"true"  CARGO_PROFILE_RELEASE_PANIC=3D"abort"=20
CARGO_PROFILE_RELEASE_CODEGEN_UNITS=3D1

Commit d697653cffd19ddaf3cdee2589a830c72ab39777 broke this functionality
