Description

Reviewing bin/bootstrap_toolchain.py while fixing IMPALA-10646 revealed that it checks the OS minor version only when running on Ubuntu. On all other supported platforms (Suse, Centos, Red Hat) the code is happy with just the major version.
https://github.com/apache/impala/blob/master/bin/bootstrap_toolchain.py#L92-L98 reveals that minor versions are irrelevant for Ubuntu: the code happily maps toolchain versions even across major versions of Ubuntu.
My proposal is to remove the minor version check from bootstrap_toolchain.py.
