Avoid running ./configure every time?

[Alexandros Karypidis <karypid at inf dot uth dot gr>]

Hi all,

The short version:

Is there a way I can have two sets of Makefiles prepared, by running 
"./configure" with different options twice (once for the native version and 
once for the cross-compile version) and to switch between then quickly?

The long version:

I've been developing some stuff which I run on an iPaq for a while now. The 
cycle I use is:

1) Do a lot of work on my desktop
2) Cross-compile for ARM
3) Transfer to iPaq
4) Test

My problem is that step (2) takes a significant amount of time. My project is 
split into several sub-projects, each with its own build system. That means 
that I have to run "./configure" for each sub-project and then re-build 
everything. I was wondering:

Is there a way I can have two sets of Makefiles prepared, by running 
"./configure" with different options twice (once for the native version and 
once for the cross-compile version) and to switch between then quickly?

To err is human, but to forgive is beyond the scope of the Operating System...
