 The problem was that I had built my base system with "./build.sh .. -V
 HAVE_LIBGCC_EH=no ..." for better clang support.
 
 The rust bootstrap should really be built with -static-libgcc.
 
 
 When I don't do that, rust still fails to build, but differently:

 From the error message I guessed that /proc needs to contain a procfs,
 and that seems to make the build proceed.
