Current evaluation

Merged PR #532 in commit 9f8e969e, adding build-on/build-for architecture and triplet variables, deprecating CRAFT_TARGET_ARCH and CRAFT_ARCH_TRIPLET, and fixing #514.

Resolution: closed resolved

Reason: PR #532 was merged as commit 9f8e969e and implemented the variables requested by issue #514. Current code exports all four build-on/build-for variables and marks the two legacy names deprecated.

Issue body

Existing `CRAFT_TARGET_ARCH` and `CRAFT_ARCH_TRIPLET` refer to the architecture we're building for. To align with the build-on/build-for naming convention and to give users access to both architectures when defining override scripts and environments, set new environment variables: ``` New environment variable Deprecated name ------------------------ ------------------ CRAFT_ARCH_BUILD_ON n/a CRAFT_ARCH_BUILD_FOR CRAFT_TARGET_ARCH CRAFT_ARCH_TRIPLET_BUILD_ON n/a CRAFT_ARCH_TRIPLET_BUILD_FOR CRAFT_ARCH_TRIPLET ``` Fixes #514.
