Enable building libgcc with CET options.
Enable building libgcc with CET options by default on Linux/x86 if
binutils supports CET v2.0. It can be disabled with --disable-cet.
It is an error to configure GCC with --enable-cet if bintuiils
doesn't support CET v2.0.
ENDBR instruction is added to __morestack_large_model since it is
called indirectly.
