Reverting commit e2f4d85d5b2049a90859aa10de914ed31a4f17a4, "crypto:
serpent - add common glue code for avx and sse2 implementation",
should help for most.

Attached patch should solve these (patch depends on above revert).
I'm really sorry about this, it shouldn't have happened. The most easiest
solution to this problem would be to make the choice between
CRYPTO_SERPENT_SSE2_X86_64 and CRYPTO_SERPENT_AVX_X86_64 an
exclusive-or choice
in crypto/Kconfig. I don't think there is an use-case, where somebody would
want to link both implementations into the same kernel image or even
load both
implementations as module. This would avoid duplicating the glue-code again.
I'd think that most common use-case is distro-kernel, where all and
everything is enabled by default.
Another possibility would be to add a serpent-common-x86_64 module, but this
wouldn't be a trivial change and imo a little bit too much just to avoid
duplicating this code.
I'm working on patch-set that takes common glue code from
serpent-sse2, serpent-avx, twofish-3way, twofish-avx and
camellia-x86_64, to shared ablk_helper and glue_helper modules.
