[Buildroot] [PATCH] linux: Fix powerpc64le defconfig selection

 > Fix up the defconfig used in this case. This will avoid the following

 >  VDSO32A arch/powerpc/kernel/vdso32/sigtramp.o
 >  cc1: error: ‘-m32’ not supported in this configuratioin
 >  make[4]: *** [arch/powerpc/kernel/vdso32/Makefile:49:
 > arch/powerpc/kernel/vdso32/sigtramp.o] Error 1

 >  http://autobuild.buildroot.net/results/dd76d53bab56470c0b83e296872d7bb90f9e8296/

 > Note that the failure indicates the toolchain is configured to disable
 > the 32 bit target, causing the kernel to fail when building the 32 bit
 > VDSO. This is only a problem on the BE kernel as the LE kernel disables
 > CONFIG_COMPAT, aka 32 bit userspace support, by default.

Committed to 2022.02.x, thanks.
