ANDROID: re-enable BIG_ENDIAN in allmodconfig testing

Revert "ANDROID: Fix arm64 allmodconfig build"
This reverts commit 099f0261d93727c97aa0dea2ed22bedf991fe574.

Proper KCONFIG checks were add in

commit e9c6deee00e9 ("arm64: Make CPU_BIG_ENDIAN depend on ld.bfd or
ld.lld 13.0.0+")

in v5.12-rc1 for ARCH=arm64, and

commit 28187dc8ebd9 ("ARM: 9025/1: Kconfig: CPU_BIG_ENDIAN depends on
!LD_IS_LLD")

for ARCH=arm in v5.11-rc1.

LLD recently gained support to link ARCH=arm64 BIG_ENDIAN. It does not
yet have support for ARCH=arm, but the Kconfig guards will prevent that
from being selected.  There's some additional complexity to support both
BE32 and BE8 in LLD, but never say never.
