Similar to commit 28187dc8ebd9 ("ARM: 9025/1: Kconfig: CPU_BIG_ENDIAN depends on !LD_IS_LLD"), ld.lld does not support aarch64 big endian, leading to the following build error when CONFIG_CPU_BIG_ENDIAN is selected:
ld.lld: error: unknown emulation: aarch64linuxb
There are not currently plans to implement big endian support for aarch64 in ld.lld but if it should be supported in the future, this symbol can depend on the version that first supports it. In the meantime, prevent this symbol from being selected to avoid these type of build errors.
While we are here, the indentation of this symbol used spaces since its introduction in commit a872013d6d03 ("arm64: kconfig: allow CPU_BIG_ENDIAN to be selected"). Change it to tabs to be consistent with kernel coding style.
