Building executables with debug symbols

[Matt Seitz <seitz metadata-systems com>]

I want to build an RPM package with executables that contain debugging 
symbols.  I believe I need to redefine the default "__os_install_post" 
macro to remove the "brb-strip" and "brp-strip-comment-note" commands. 
In what part of the spec file should I redefine "__os_install_post"?

Also, I an concerned about simply defining a fixed "__os_install_post", 
since it is possible that different systems may have different default 
"__os_install_post" macros.  Is there a way I can simply remove the 
"brp-strip" and "brp-strip-comment-note" portions of the default macro 
and leave the rest intact?
