I can't build this, it fails with

  LD [M]  arch/powerpc/crypto/p10-aes-gcm-crypto.o
powerpc64le-linux-gnu-ld: arch/powerpc/crypto/p10_aes_gcm.o: ABI version 2 is not \
                compatible with ABI version 1 output
powerpc64le-linux-gnu-ld: failed to merge target specific data of file \
arch/powerpc/crypto/p10_aes_gcm.o
