1) When speccifying an architecture using -xarch/-xtarget, it needs to
come before the compilation type (e.g. -fast) flags
2) It makes it hard to build 64-bit builds using -xarch=v9,v9a and v9b.
Suggestion from Tomas Puverle.

in favour of the latter (toolset.prebuilt). This cuts down the number
of generator invocations for prebuilt target and is more clear.
Thanks to Mark Evans for pointing this out.

1. If when generating something, we find more that one suitable generators,
run them and more then one return something, immediately report ambiguity.
Don't care if the produced targets are the same. This is better that
running several generators all the time, performance wise.
2. Remove the notion of 'intermediate' virtual-targets. IIRC, they were used
to prevent staging of RSP files, and we don't stage them anyway now.

libraries in a chain. E.g. in app -> a.so -> b.so, we need to pass
the path to b.so to the linker so that it can verify that all symbols
asked by 'app' and 'b.so' are present.

the compiler does not have a switch to change the source language, so we
take the command and replace the filename in the last element with 'cc'.
