Subject: Only create ${CT_TARGET}-cc${ext} symlink if ${CT_TARGET}-gcc exists

Without this canadion cross builds create invalid symlinks:
When the code in do_cc_core_backend is called there is no
${CT_TARGET}-gcc in the install directory. Therefore ext is empty and
we create a link to ${CT_TARGET}-gcc. The final compiler
step then installs ${CT_TARGET}-gcc.exe and creates a working
${CT_TARGET}-cc.exe symlink but we still keep the invalid link
as well.
