adwaita-icon-theme: fix rare install race
There have been rare errors during the build of adwaita-icon-theme, such as: Exception: bb.process.ExecutionError: Execution of '.../temp/run.sysroot_stage_all.45186' failed with exit code 2: cpio: ./icons/Adwaita/32x32/legacy/_inst.34160_: Cannot stat: No such file or directory cpio: ./icons/Adwaita/32x32/legacy/_inst.33428_: Cannot stat: No such file or directory cpio: ./icons/Adwaita/32x32/legacy/_inst.35421_: Cannot stat: No such file or directory cpio: ./icons/Adwaita/32x32/legacy/_inst.34533_: Cannot stat: No such file or directory cpio: ./icons/Adwaita/32x32/legacy/_inst.35366_: Cannot stat: No such file or directory The problem was that a previous optimisation (oe-core cd9af17028) to massively increase the install speed (by parallelling the hundreds of installs) was subtly wrong. It was essentially doing this: for i in list; do install i & done wait In pure shell this does parallelise the install commands and then wait for them all to finish before exiting, but in Makefiles *each line in a separate shell*. The actual Makefile is closer to this: for i in list; do \ install i & \ done wait The backslashes are required to write a multi-line for loop in a Makefile, but note that when the loop ends the shell exits and all of the install processes that are still running are disowned. The wait command then executes in a new shell, and there are no childen to wait for. The fix is trivial: add more backslashes so that the wait is part of the same shell.
