[Asterisk-Dev] PATCH: Add DESTDIR support to makefiles

[Jake Morrison]

I have added DESTDIR support to the Asterisk makefiles.

The patch file is attached in bugs.digium.com:

DESTDIR is a standard makefile variable used to install
files to a temporary staging directory, from which the 
files will be copied to their final installed location. 
 
It is useful for building packages like RPMs, 
debs or xBSD ports. It can also be used to 
build on one machine, tar up the resulting files 
and install them on another machine.
 
It is different from INSTALL_PREFIX, which specifies
a prefix for the final location of the installed files. 
 
Usage: make DESTDIR=/my/staging/dir install
