Improve CPPFLAGS usage

Browse Source 
CPPFLAGS was dropped[1] back on 2004-04-24. Then a workaround was
introduced by commit 6d7e9bfe5b to fix
compilation on FreeBSD that used CPPFLAGS to store iconv related flags.
The use of CPPFLAGS with respect to the COMPILE "macro" reappeared in
40e257bedd on 2006-08-05.

This commit makes configure.in print CPPFLAGS and LDFLAGS. Before,
CPPFLAGS and CFLAGS was mixed together in the feature summary. It also
restores the use of CPPFLAGS storing iconv related flags but keeps the
use of the SAVE/RESTORE_FLAGS in the iconv macro.

Reported by Daniel E. Macks <dmacks@netspace.org> on 2005-11-22 in a mail
to elinks-users with the ID: <slrnem7tjs.lvk.dmacks@happy.netspace.org>.
