The Xen compile checks are currently run inside subshells. This
is unnecessary and has the effect that if do_cc() exits with
an error message then this only causes the subshell to exit,
not the whole of configure, which is confusing. Remove the
subshells, changing:
if ( cat ; compile_prog ) ; then ...
to
if cat && compile_prog ; then ...
