You're no longer removing just binaries :)

I think a slightly more Buildroot-ish way to do this is:

	rm -f $(addprefix $(TARGET_DIR)/usr/bin/, \
	        clang* c-index-test git-clang-format scan-build scan-view)

and ditto for the others. Or perhaps, even more readable:

CLANG_FILES_TO_REMOVE = \
	/usr/bin/clang* \
	/usr/bin/c-index-test \
	/usr/bin/git-clang-format \
	/usr/bin/scan-build \
	/usr/bin/scan-view \
	...

and:

define CLANG_CLEANUP_TARGET
	rm -f $(addprefix $(TARGET_DIR),$(CLANG_FILES_TO_REMOVE))
endef

Best regards,

Thomas
