GCC does not, but Autoconf and Bison for example do. GCC's templates are a handful of instructions long (at most) and are subject to plenty of transformations before they end up in assembly code; Autoconf and Bison literally copy hundreds of lines of code verbatim. You need a license that is separate from the GPL to use that output in a non-GPL-compatible derivative work.

That makes sense - if autoconf source is closer to a set of instructions "please include library functions A, E and G in this order" than C source, it's obvious that each function is under copyright and so the output would come under the terms of the license covering those functions.
