Retire CT_CC_GCC_TARGET_FINAL

Browse Source 
Make this behavior default in case the core gcc backend is used
for final compiler (i.e., for baremetal configurations). Not
setting this option breaks canadian baremetal configurations,
and not setting it makes little sense at all in any baremetal
configuration (since in baremetal we don't have any libc to begin
with).

The final GCC for a bare metal system is built by the core gcc script.
This script does a lot of tricks to build the core gcc, which are not
required for the final gcc build. If you set this flag to true, all the
tricks are not done and the compiler is build with all/install.
