Okay, thanks for the help guys.  So, I switched over to a linux box:

uname -a
Linux iapetus 2.6.33.6-147.fc13.x86_64 #1 SMP Tue Jul 6 22:32:17 UTC 2010
x86_64 x86_64 x86_64 GNU/Linux


and  I am running into similar problems.  I am building synthetic target
'i386linux'.  When I do make inside the buildtree, I get
i686-pc-linux-gnu-gcc not found.

To get around this problem, I modified ecos.ecc so that the Command prefix
returns an empty string.

After that, I run into a similar problem at the assembly stage:

make[1]: Entering directory

So do you have any further suggestions?
