Not true, as Debian must provide Emacs source code, including
lisp/progmodes/compile.el.  You could patch that and recompile it, since
compile.elc isn't dumped into the emacs executable.  Or you could copy
it to your site-lisp directory (or other directory in your load-path),
then patch and compile the copy.

Wow, I didn't know compile-command could be an expression that is
evaluated dynamically!  That feature is not documented in the variable's
doc string, the Emacs manual, or the NEWS file -- which in itself is a
bug.
