Subject: [PATCH v7 06/15] bugreport: add compiler info

From: Emily Shaffer <[email-masked]>
Date: Thu, 13 Feb 2020 17:53:34 -0800

To help pinpoint the source of a regression, it is useful to know some
info about the compiler which the user's Git client was built with. By
adding a generic get_compiler_info() in 'compat/' we can choose which
relevant information to share per compiler; to get started, let's
demonstrate the version of glibc if the user built with 'gcc'.
