Subject: [PATCH 5.15 177/279] powerpc: clean vdso32 and vdso64 directories

From: Masahiro Yamada <masahiroy@...nel.org>

[ Upstream commit 964c33cd0be621b291b5d253d8731eb2680082cb ]

Since commit bce74491c300 ("powerpc/vdso: fix unnecessary rebuilds of
vgettimeofday.o"), "make ARCH=powerpc clean" does not clean up the
arch/powerpc/kernel/{vdso32,vdso64} directories.

Use the subdir- trick to let "make clean" descend into them.

Fixes: bce74491c300 ("powerpc/vdso: fix unnecessary rebuilds of vgettimeofday.o")
