Package: binutils
Version: 2.21.51.20110419-2
Severity: grave
GNU as documentation says about the -mcpu option for ARM:
The special name `all' may be used to allow the assembler to
accept instructions valid for any ARM processor.
However, this no longer works, resulting in failure to build Linux on
ARM:

The command line is:

Changing '-march=all' (which is not explicitly documented) to
'-mcpu=all' makes no difference.
This regression appears to have happened since binutils
2.21.0.20110327-2, as that appears to have been used to build
linux-2.6 version 2.6.38-3.
