Subject: support/testing: add tests for Rust
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e9429539ec819ab32f73414deb05af632a9405cf;p=buildroot.git

support/testing: add tests for Rust

To test the support for the Rust language, the following tests are added:

- building Rust compiler and Cargo from source.
- installing a pre-built Rust compiler and building Cargo from source.

For each test, a Rust test program is built and installed in the root file
system of a ARM vexpress QEMU system. The test is declared OK if the program can
be run properly from the test system.
