Subject: buld-sys: simplify configure script; drop unused checks.

With this change, configure is updated to a more modern syntax, a number of
tests possibly introduced by autoscan are dropped (as the code never makes
use of those), and comments are changed with dnl's so that they are not
copied in the final output.
