This commit is for linux-4.19.y only, it has no direct upstream
equivalent.
Prior to commit 5f2fb52fac15 ("kbuild: rename hostprogs-y/always to
hostprogs/always-y"), always-y did not exist, making the backport of
mainline commit 1b1e38002648 ("powerpc: add crtsavres.o to always-y
instead of extra-y") to linux-4.19.y as commit b7b85ec5ec15 ("powerpc:
add crtsavres.o to always-y instead of extra-y") incorrect, breaking the
build with linkers that need crtsavres.o:
ld.lld: error: cannot open arch/powerpc/lib/crtsavres.o: No such file or directory
Backporting the aforementioned kbuild commit is not suitable for stable
due to its size and number of conflicts, so transform the always-y usage
to an equivalent form using always, which resolves the build issues.
Fixes: b7b85ec5ec15 ("powerpc: add crtsavres.o to always-y instead of extra-y")
