Use the new BYTECODE_DESTINATION to override the default bytecode install
destination for this library so that it goes to $(cferuntime_libdir) rather
than just $(libdir). Normal bytecode libraries should be installed in the
$(libdir), but these ones are "special" because they're part of the the
C/C++ front end.

More properly name bytecode_libdir cferuntime_libdir. This is only the
libdir for the CFE runtime libraries, not "all bytecode".

Finish the implementation of the BYTECODE_DESTINATION feature for modules
too and getting rid of the last remnants of bytecode_libdir.

Implement a new feature, BYTECODE_DESTINATION, to allow a user makefile to
specify where the bytecode library is to be installed. This allows the
default location ($prefix/lib) to be overridden, for special case runtime
libraries like the cfe runtime libs.
