dietlibc not available on lpia

[Thorsten Glaser]

Binary package hint: dietlibc

There is no dietlibc on lpia, which I understand is the same machine
architecture as i386 but optimised for low power consumption.

It should be possible to fool dietlibc into thinking lpia==i386, or even
use the i386 binary package on lpia.

The mksh package comes with /bin/mksh-static, which is linked against
dietlibc if available and would benefit from that.

The lpia architecture has been retired, so there should be no further need to work on this.
