With this patch in the tree, trying to build ppc:allmodconfig
with gcc version 13.3 and binutils version 2.42 results in:

Error log:
/tmp/cccUl45i.s: Assembler messages:
/tmp/cccUl45i.s: Error: .size expression for gcm_init_p8 does not evaluate to a constant

and many other similar messages. The problem affects various drivers in
drivers/crypto/vmx/. The problem afects all configurations with CRYPTO_DEV_VMX_ENCRYPT
enabled.

Reverting the patch doesn't work because this patch is part of a larger series. However,
I found that applying upstream commit 505ea33089dc ("powerpc/64: Add big-endian ELFv2
flavour to crypto VMX asm generation") fixes the problem.
