Problem running source builder

[Simon Williams]

Thanks Sebastian, your question about where it got the binutils from put me
on the right track.  The binutils that it was picking up were the ones that
I built on January 9.  I removed the directory from my PATH and still had
the problem, so I looked in the log and discovered that there are several
paces where the build is adding the target bin directory to the PATH, so I
renamed the original $PREFIX directory and that solved the issue.  It
appears that source builder doesn't like building into a location that
already contains a tool chain.

Until recently, I have been using MING32 on Windows and so was using
pre-built tools.  It may be that this is a known limitation, please excuse
my ignorance if it is.

Regards

Simon
