What is the current behavior?

Until 0.5.2 the exporter was working. since 0.6.0 the exporter requires glibc-2.32 or later which is not available for OracleLinux 8.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

/u03/prometheus/exporter/oracledb_exporter/oracledb_exporter: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by /u03/prometheus/exporter/oracledb_exporter/oracledb_exporter)

What is the expected behavior?

The exporter should work using glibc-2.28-*

What is the motivation / use case for changing the behavior?

Same for Rocky Linux 8 (having 2.28 here)

Building without glibc using CGO_ENABLED=0 env variable fix the issue on oracle linux 8.
Would be nice to include a no-glibc version in the releases so it can run on older systems
