Subject: [PATCH] Remove cruft from B's Makefile.PL

$noecho is unused since 70c68212ed57a5a0 (in 2005)
$e and $exeout_flag are unused since e8edd1e67bd80dbb (in 1999)
All the clean FILES apart from 'defsubs.h' are vestigial or duplicate defaults.
The rule for LIBS created by post_constants() seems superfluous.
