On Windows, with a fresh clean install of arm-none-eabi-gcc, building cortex-m-rt eventually fails with:

Internal error occurred: Failed to find tool. Is `ar` installed? (see https://github.com/alexcrichton/cc-rs#compile-time-requirements for help)

As a workaround, setting the TARGET_AR environment variable to arm-none-eabi-ar fixes it. This was not necessary before, and is not documented anywhere if it is a new requirement.

I just bumped into this as well, thanks for the workaround.

IMO, cc should be using a prefixed archiver if already using a prefixed compiler / assembler. I have filed rust-lang/cc-rs#330 to request changing the behavior.
