The CONFIG_PROPELLER_CLANG option currently depends on
ARCH_SUPPORTS_PROPELLER_CLANG, but this dependency seems unnecessary.
Remove ARCH_SUPPORTS_PROPELLER_CLANG and allow users to control
Propeller builds solely through CONFIG_PROPELLER_CLANG. This simplifies
the kconfig and avoids potential confusion.
Move the .llvm_bb_addr_map sections grouping to
include/asm-generic/vmlinux.lds.h.
The Propeller documentation has been updated to reflect the most
recent tool location and now includes instructions for arm64.
