--- Comment #4 from Pierre Ossman <ossman at cendio dot se> ---
I assumed that this would be what happened:

 Given --build=B --host=H and --target=T:

 1. A gcc would be configured with --build=B --host=H --target=T and put in the
installation directory.

 2. A second gcc would be configured with --build=B --host=B --target=T and
used to build all the libraries that execute on the target system (libgcc,
libstdc++, libobjc, etc.).

But I guess what you are saying is that only the first compiler is built, and
if B != H then you use the system compiler to build the libraries? But how
could that possibly work given that you will then produce libraries for H, not
T?
