signal: use BUILD_BUG() instead of _NSIG_WORDS_is_unsupported_size() Kill _NSIG_WORDS_is_unsupported_size(), use BUILD_BUG() instead. This simplifies the code, avoids the nested-externs warnings, and this way we do not defer the problem to linker. Also, fix the indentation in _SIG_SET_BINOP() and _SIG_SET_OP(). Note: this patch assumes that the code like "if (0) BUILD_BUG();" is valid. If not (say __compiletime_error() is not defined and thus __compiletime_error_fallback() uses a negative array) we should fix BUILD_BUG() and/or BUILD_BUG_ON_MSG(). This code should be fine by definition, this is the documented purpose of BUILD_BUG().
