bootstrap -j 2 failure for gcc 3.4.1 20040602 on i686-linux: make[4]: stage2/xgcc: Command not found

[Christian Joensson <christian at j-son dot org>]

A recent change to the 3.4 tree (now at 3.4.1) makes it not bootstrap
at j -2 (and I assume greater).

The problem did not show at LAST_UPDATED: Tue Jun 1 06:19:29 UTC 2004,
see http://gcc.gnu.org/ml/gcc-testresults/2004-06/msg00023.html, but
occurs now at LAST_UPDATED: Wed Jun 2 06:13:21 UTC 2004... so the
failure causing candidates are, hmm, not easy to understand...

This was the output from gcc_update was this:

So I guess that the problem was introduced before... I can't find
anything that points towards a cause of the problem. I suspect race
conditions related to configure/Makefile changes... or hw problems?...
