precompile failure with IO redirection

[iblislin]

I can reproduce this on both Linux and FreeBSD.

$ (g)make > /tmp/test.log

and got this on stderr:

JULIA usr/lib/julia/sys-o.a
fatal: error thrown and no exception handler available. 
ErrorException("Task cannot be serialized")

This issue make some buildtools unhappy, like poudriere, which serves with the
FreeBSD package binaries.

Thanks for reproducer. This is likely what makes Nanosoldier unhappy as well @ararslan. Will look at it.

Ah, just found the link about Nanosoldier on Slack.

I assume this occurs because the precompile generator thing relies on output redirection?

[KristofferC]

The output redirection for the precompilation generation process should be fully isolated from that though. But apparently not. Looking at it now.
