#     powerpc: Allow CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2 with ld.lld 15+
#     
#     Commit 5017b4594672 ("powerpc/64: Option to build big-endian with ELFv2
#     ABI") restricted the ELFv2 ABI configuration such that it can only be
#     selected when linking with ld.bfd, due to lack of testing with LLVM.
#     
#     ld.lld can link ELFv2 kernels without any issues; in fact, it is the
#     only ABI that ld.lld supports, as ELFv1 is not supported in ld.lld.
#     
#     As this has not seen a ton of real world testing yet, be conservative
#     and only allow this option to be selected with the latest stable release
#     of LLVM (15.x) and newer.
#     
#     While in the area, remove 'default n', as it is unnecessary to specify
#     it explicitly since all boolean/tristate configuration symbols default
#     to n.
