    Enable Intel CET in liblto_plugin.so on Intel CET enabled host · 8fc8bf80
    H.J. Lu authored
    Since ld is Intel CET enabled on Intel CET enabled host, dlopen fails on
    liblto_plugin.so if it isn't Intel CET enabled.  Add GCC_CET_HOST_FLAGS
    to cet.m4, use it in libiberty and lto-plugin to always enable Intel
    CET in liblto_plugin.so on Intel CET enabled host.
    
    On Linux/x86 host, enable Intel CET by default if assembler and compiler
    support Intel CET so that the generated liblto_plugin.so can be used on
    both CET and non-CET machines.  It is an error to disable Intel CET in
    liblto_plugin.so on Intel CET enabled host.
