New description:
This is essentially #13407 for upgrades: `sage-make_relative` is evil
because it leads to race conditions.
This probably caused an upgrade problem on `rosemary`: the script
`local/bin/ipython` wasn't installed:
{{{
running install_scripts
copying build/scripts-2.7/iplogger ->
/home/buildbot/build/sage/rosemary-1/rosemary_upgrade_4.5.2/build/sage-5.7.beta1/local/bin
}}}
which normally looks like
{{{
running install_scripts
copying build/scripts-2.7/ipengine ->
/release/buildbot/sage/sage-1/sage_upgrade_4.8/build/sage-5.7.beta1/local/bin
copying build/scripts-2.7/ipcontroller ->
/release/buildbot/sage/sage-1/sage_upgrade_4.8/build/sage-5.7.beta1/local/bin
copying build/scripts-2.7/ipcluster ->
/release/buildbot/sage/sage-1/sage_upgrade_4.8/build/sage-5.7.beta1/local/bin
copying build/scripts-2.7/iplogger ->
/release/buildbot/sage/sage-1/sage_upgrade_4.8/build/sage-5.7.beta1/local/bin
copying build/scripts-2.7/ipython ->
/release/buildbot/sage/sage-1/sage_upgrade_4.8/build/sage-5.7.beta1/local/bin
copying build/scripts-2.7/pycolor ->
/release/buildbot/sage/sage-1/sage_upgrade_4.8/build/sage-5.7.beta1/local/bin
copying build/scripts-2.7/irunner ->
/release/buildbot/sage/sage-1/sage_upgrade_4.8/build/sage-5.7.beta1/local/bin
copying build/scripts-2.7/iptest ->
/release/buildbot/sage/sage-1/sage_upgrade_4.8/build/sage-5.7.beta1/local/bin
}}}
Distutils by default doesn't overwrite newer files, and `sage-
make_relative` can make a file look newer, causing `distutils` to not copy
a file.
