[src/trunk]: src/tools/gcc - Generate a list of CPP flags used to build *.o. ...

[uebayasi <uebayasi%NetBSD.org@localhost>]

details:   https://anonhg.NetBSD.org/src/rev/3db4c4c8f76e
branches:  trunk
changeset: 749446:3db4c4c8f76e
user:      uebayasi <uebayasi%NetBSD.org@localhost>
date:      Mon Nov 30 07:08:03 2009 +0000

description:
- Generate a list of CPP flags used to build *.o.  Some files are build
  repeatedly with different -DXXX to generate similar objects (e.g. different
  type size).

- Generate a list of other CC options to build *.o.

(See my sed-fu using hold space in get_libgcc_list_objs_xflags().)
