[Evolution] Leaving debug symbols in

[Bob Purvy <bpurvy gmail com>]

apologies for this newbie question, but:

How do I keep the symbols from getting removed on 'make install' ?
I'm using 2.4.2.1, which I know is way old, but I have to use it for
reasons you don't want to know.

I can tell that 'strip' is getting called, but i can't figure out how.
 I went as far as to copy the 'touch' executable over 'strip', but
that still didn't do it.
