Fix rebuilding docs, by hiding __attribute__((...)) behind a macro. When enabled via `./configure --enable-rebuild-docs`, `make -C doc libxml2-api.xml` will invoke apibuild.py to rebuild libxml2-api.xml from the sources. But the code added in 9fa3200cb366c726f7c8ef234282603bb9e8816d made it error out with ``` Parsing ../parser.c Parse Error: parsing type : expecting a name ('Got token ', ('sep', '(')) ('Last token: ', ('sep', '(')) ('Token queue: ', [('name', 'destructor'), ('sep', ')'), ('sep', ')')]) ('Line 14689 end: ', '') ```
