Description:
The provided mysql community builds for mysql 8.0 on RHEL7 seem to be missing the "debug" builds. The mysqld binaries that are shipped have an enormous size of >1GB

After "strip"ing them, they are at 60mb for mysqld and 120mb for mysqld-debug

How to repeat:
Use RHEL 7 / CentOS 7

Install MySQL Repo from https://dev.mysql.com/downloads/repo/yum/
Install MySQL Server: yum install mysql-community-server

ls -la /usr/sbin/mysql*
-rwxr-xr-x 1 root root 1160290352 Jun 16 19:56 /usr/sbin/mysqld
-rwxr-xr-x 1 root root  756117752 Jun 16 19:36 /usr/sbin/mysqld-debug

Suggested fix:
Change rpm spec to build seperate debug packages or at least do a "strip" on the binary files.

## imho most of the size is caused by debug symbols, there was some internal discussion happening

This is nothing to do with rpm builds but this can be even seen in binary tarball builds. Imho most of the size is caused by debug symbols and this looks like reasonable feature request to reduce the size.
