cmake: Define _GNU_SOURCE before checking for any symbols

Simon McVittie requested to merge smcv/dbus:wip/issue453 into master

  • cmake: Define _GNU_SOURCE before checking for any symbols

    Some of the symbols we check for, such as close_range(), are only declared in their corresponding header files if _GNU_SOURCE was defined.

    Resolves: #453 (closed)

  • sysdeps: Correct fallback signature of Linux close_range()

    Linux generally declares syscalls with flags as type int. It's the same ABI, but a slightly different API, and it seems better for our fallback definition to match it exactly.

    Related to #453 (closed).

Ready for review, but please don't merge until after I've released 1.15.8.

Not applicable to 1.14.x or older.
