Fix configuration system to support different architectures on Cygwin.

This patch allows to recognize the architectures supported by Cygwin
and to choose the right configuration from there.  Drop -march to
use default architecture on 32 bit x86.

Drop pre-Cygwin-1.3 recognition since it's long gone and there's no
valid configuration for this anymore.
