Hi,

I'd suggest that wineboot checks the value of WINEARCH when creating a new
prefix Wine, and errors out with a nice error message if WINEARCH is unknown
(neither empty, nor win32 or win64).

Currently I think there's only a test if #arch in system.reg is valid.

This check especially helps new users who confuse win32 and wine32, e.g.:

$ rm -rf .wine
$ export WINEARCH=wine32
$ wineboot
wine: created the configuration directory '/home/jens/.wine'
[...]
wine: configuration in '/home/jens/.wine' has been updated.
$ grep #arch .wine/system.reg 
#arch=win64
