[PATCH 2/4] scripts/Kconfig.toolchain: Do not dynamically probe '-fno-addrsig'

[Nathan Chancellor]

'-fno-addrsig' avoids generating the LLVM specific .llvm_addrsig
section. This flag is supported by all supported versions of clang, so
convert CONFIG_CC_OPT_NO_ADDRSIG into a simple string symbol that
depends on CC_IS_CLANG to clean up a dynamic probe that is unnecessary.
