Below reproducer instructions can be used to re-build both "first_bad" and "last_good" cross-toolchains used in this bisection.  Naturally, the scripts will fail when triggerring benchmarking jobs if you don\'t have access to Linaro TCWG CI.

Configuration:
- Benchmark: EEMBC CoreMark
- Toolchain: GCC + Newlib + GNU LD
- Version: all components were built from their tip of trunk
- Target: arm-eabi
- Compiler flags: O3
- Hardware: STMicroelectronics STM32L476RGTx 1x Cortex-M4

This benchmarking CI is work-in-progress, and we welcome feedback and suggestions at linaro-toolchain@lists.linaro.org .  In our improvement plans is to add support for SPEC CPU2017 benchmarks and provide "perf report/annotate" data behind these reports.
