Details:
I didn't build avr-libc so I don't know when this (mis)feature appeared...
The top level configure script requires to spell out --host=avr. IMHO this is
unfortunate for several reasons:
1) the product is called avr-libc. I wouldn't expect it to provide anything
else (e.g. a libc for ARM) than a libc for avr. Nevertheless you have to type
that option altough the only permitted value is 'avr*'
2) It is a library for my 'target', not for my 'host'. The hosting machine
typically is a Linux or Windows PC. That's why I stumbled over this issue in
the first place. I naivly tried "./configure --target=avr" as for binutils and
gcc and it failed. (I can vaguely imagine a logic why it is called host, but
that's very counterintuitive!)
3) I had a third reason when I opened the issue but I don't remember
anymore...
I propose to accept --target= as an equivalent to --host in the first step,
correct the build instructions and then to deprecate --host as a target
indicator (it might still be useful for an alternative name of --build in case
config.guess fails to correctly detect the hosting machine)
