Pull request overview

This PR adds compile-time diagnostic checks to investigate issue #123950. The changes introduce #error directives that will fail Linux builds if the HAVE_PTHREAD_CONDATTR_SETCLOCK and HAVE_CLOCK_MONOTONIC features are not available.

Changes:

• Added #error directives in the fallback code paths for pthread condition attribute initialization on Linux
• These checks are placed in two synchronization-related files: System.Native threading primitives and CoreCLR's synchronization manager

This commented-out error directive should either be removed or uncommented. Having commented-out preprocessor error directives in the codebase can be confusing and suggests incomplete investigation work. If this check is needed, it should be active; if not, it should be removed entirely.

Suggested change

//#error HAVE_CLOCK_MONOTONIC missing
