-Description: revert upstream commit that removes use of syscall() and statx(2)
- The commit https://code.qt.io/cgit/qt/qtbase.git/commit/?id=b7887f9b4faad222
- removes the use of the above mentioned syscalls. This makes Qt not able
- to run on current stable servers under a testing/unstable VM.
- .
- This patch should be removed in testing/unstable after Buster gets released.

-This adds the necessary bits to make qt attempt building webengine on ppc64.
-Since the patch is only sufficient for ppc64le, keep it commented out and
-let the packaging template remove the comment later, as there is no good
-way to check endianness directly in the file.
-
-We also have to disable jumbo build for the time being because it results
-in build failures otherwise, most likely because of compiler miscompiling
