faketime: add patch to disable -Werror
faketime currently doesn't build on host machines that use gcc 8.x due to stricter checks done by gcc, and the fact that it is built with -Werror. As a simple stop-gap measure, this commit patches the faketime Makefile to not use -Werror anymore. The actual fixes for the gcc 8.x issues have been submitted upstream at https://github.com/wolfcw/libfaketime/pull/161, but disabling -Werror is a much smaller fix. Also, it is worth mentioning that removing -Werror makes the existing patch 0001-Disable-the-non-null-compare-warning-error.patch (which was just disabling one specific warning). We nonetheless keep this patch around as it is a backport from upstream.

Subject: [PATCH] src/Makefile: disable -Werror
|
||||
|
||||
gcc 8.x has enabled additional warnings that break the build due to
|
||||
-Werror, so let's drop -Werror for now. A set of patches has been
|
||||
submitted upstream (https://github.com/wolfcw/libfaketime/pull/161) to
|
||||
properly fix the gcc 8.x issues, but in the mean time, disabling
|
||||
-Werror is a simpler option.
