#     tools: compiler-gcc.h: Guard error attribute use with __has_attribute
#     
#     When building objtool with HOSTCC=clang, there are several errors along
#     the lines of
#     
#       orc_dump.c:201:28: error: unknown attribute 'error' ignored [-Werror,-Wunknown-attributes]
#     
#     This occurs after commit 4e59869aa655 ("compiler-gcc.h: drop checks for
#     older GCC versions"), which removed the GCC_VERSION gating.  The removed
#     version check just so happened to prevent __compiletime_error() from
#     being defined with clang because it pretends to be GCC 4.2.1 for
#     compatibility but the error attribute was not added to clang until
#     14.0.0.
#     
#     Commit 815f0ddb346c ("include/linux/compiler*.h: make compiler-*.h
#     mutually exclusive") and commit a3f8a30f3f00 ("Compiler Attributes: use
#     feature checks instead of version checks") refactored the handling of
#     attributes in the main kernel to avoid situations like this but that
#     refactoring has never been done for the tools directory.
#     
#     Refactoring is a rather large undertaking and this has never been an
#     issue before so instead, just guard the definition of
#     __compiletime_error() with __has_attribute() so that there are no more
#     errors.
