merge compile fixes from 44080:

- with AST_DEVMODE, building codecs/lpc10 fails because of lots
  of warnings, and the configure step in editline fails as well.
  Fix this by removing the -Werror in these steps.

- on FreeBSD (but probably on other platforms as well), the final   
  link of asterisk fails because AST_LIBS was not exported to the
  subdirs Makefiles. Add a proper fix in the top-level Makefile
  (a possible alternative way is to add "export AST_LIBS" near
  the beginning of the file).
  With this fix, i believe that some of the platform-specific
  conditionals in main/Makefile are redundant (because they should
  be already dealt with in the top level Makefile) but i don't
  have a platform to check.
