SVN commit 1039764 by ossi:

clean up event loop of gcc invocation

the sigchld handler which sets a flag is inherently racy (that's what
pselect() was introduced for, but see the linux man page for it). so
instead use a nicely synchronizing death pipe.
also, consolidate the two event loops into one.
as the code is running in a short-lived child, i made it lazy about
freeing resources for legibility's sake.
