[Bug translator/11207] New: Support preprocessor defines

["jistone at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

It would be nice to be able to #define things in our scripts, both for brevity
and additional flexibility.  There are many ways we could go about this.

One way is to incorporate this into our existing preprocessing style.  It could
look something like:

  %( define LIBFOO = "/path/to/libfoo.so" %)
  %( define FOOFUNC(f) = process.library(LIBFOO).function(f) %)

  probe FOOFUNC("*") { ... }

Another option is to just run our scripts through an existing preprocessor.  CPP
is not an option because we don't want to expand embedded-C code blocks.  It
should work to use m4 though, and maybe there are others.

One advantage of rolling our own is that it should be easier to maintain
column/line info for error reporting.
