keep compiled files between compiles, make distclean

[breznak]

1/ new target make distclean
2/ keeping precompiled objects during compilations - makes consequent builds much faster, only changed objects are recompiled.

when numenta/nupic.core-legacy#65 is merged and SHA here updated to it, the difference should be visible!

[breznak]

Actually not sure about Travis - it does delete all files at init, right? But definitely fast for user builds.

@breznak Travis has a fresh environment and fresh checkout of the repo for every job. Is that what you are asking?

[breznak]

Ok, so travis would not gain any speed-advantage from this (unless we can copy object files from last build to build/temp ) . But developers (who rebuild often) definitely would.

LGTM... @david-ragazzi ?

What is LGTM?? hehe

[david-ragazzi]

@breznak Wouldn't be better "make clean" instead of "make distclean"?

Waiting for @breznak answer..

I thought the same, but no. clean is reserved target for make. see that it already does something.
Dist clean is by convention a "hardcore version of clean", it'll remove all files from compile.

Btw, updated SHA, for the change to make sense.
