Not really.  It's the AC_PROG_{CC,CXX,...}  macros that select
appropriate default {C,CXX,...}FLAGS if the user hasn't passed
any.  You can avoid that by passing them explicitly
   ./configure CFLAGS= CXXFLAGS= ...

as user; and you can avoid the default setting as developer
by saving their value before the respective macro, and restoring
them afterwards.

Remember, the user should always be able to override the developer,
because the latter cannot know it all.
