Description

bootstrap_toolchain.py detects the OS platform the build is running on by taking the output of lsb_release -sir (or equivalent) and parsing it.
Apparently Impala was never built on Red Hat platforms before: it returns a different signature on Red Hat than on Centos despite the high degree of binary compatibility between the two distros.
This makes bootstrap_toolchain.py throw an exception, breaking the build early:
