IMPALA-11599/IMPALA-11605: GCC 10: Fix gdb and change to flatbuffers 1.9
This contains two fixes for issues introduced by
IMPALA-9999's upgrade to GCC 10:
IMPALA-11599: Builds toolchain gdb with the OS compiler,
fixing an issue where it could not run on Centos 7 due
to problems with its RPATH / finding appropriate libstdc++.
IMPALA-11605: Reverts to flatbuffers 1.9, which avoids
a mismatch with the version that Hive uses. This avoids
classpath incompatibility issues.
Testing:
- Verified that toolchain gdb works on Centos 7
- Verified that interoperability with Hive is restored

> IMPALA-9999's upgrade of flatbuffers to 1.12 causes a conflict with Hive

> Key: IMPALA-11605
> URL: https://issues.apache.org/jira/browse/IMPALA-11605
> Project: IMPALA
> Issue Type: Bug
> Components: Infrastructure
> Affects Versions: Impala 4.2.0
> Reporter: Joe McDonnell
> Assignee: Joe McDonnell
> Priority: Critical
>
> IMPALA-9999's upgrade to GCC 10.4 switched to flatbuffers 1.12 as older
> flatbuffers versions do not compile on newer GCC versions. This required
> switching the Java version as well. However, upgrading the Java version
> causes a conflict with Hive, which uses flatbuffers 1.9.
> Since Impala is upgrading in order to avoid the C++ compilation issue, we can
> resolve the conflict by using flatbuffers 1.9 and patching it with the fix
> from here:
