This has always been different between Windows and Linux:

if test "$mingw32" = "yes" ; then
    mandir="$prefix"
    datadir="$prefix"
    qemu_docdir="$prefix"
    bindir="$prefix"
    sysconfdir="$prefix"
    local_statedir=
else
    mandir="${mandir:-$prefix/share/man}"
    datadir="${datadir:-$prefix/share}"
    qemu_docdir="${qemu_docdir:-$prefix/share/doc/qemu}"
    bindir="${bindir:-$prefix/bin}"
    sysconfdir="${sysconfdir:-$prefix/etc}"
    local_statedir="${local_statedir:-$prefix/var}"
fi

See also how os_find_datadir() is different between Windows and POSIX.
I plan to fix this mess (and incidentally the pre_prefix hack) in 5.2
by making the installation relocatable.
