Problems with temporary directory space in shared environment

[ocaisa]

When I try a toolchain, eb doesn't clean up the .eb files it created in /tmp, regardless of whether the build was successful or not. In our case we have a group of people using EB on our system, which means if someone else tries to build the same software later they can't because they can't overwrite the created .eb file.

#695 can help fix this. We just need to generate a random unique prefix in $EASYBUILD_TMPDIR or use $EASYBUILD_TMPDIR/$USER/

Should be fixed in #695

We use a random directory in $EASYBUILD_TMPDIR (which defaults to /tmp).

Fixed by #695, thanks @wpoely86!
