C build seems to spend a lot of time on mbedtls test suite

[cpswan]

Describe the bug

Whilst doing a C release the build logs suggest that tests are being built and linked.

Steps to reproduce

1. First I release C sshnpd (e.g. c0.3.2)
2. Then I the build action runs
3. And then whilst waiting for a build to complete I see multiple log entries referencing tests.

Expected behavior

Tests aren't built for releases.
