Joshua Peraza 3e065b11d0 linux, mac: disable cfi-icall for cross-dso calls
CFI attempts to verify that the dynamic type of a function object
matches the static type of the function pointer used to call it.

https://clang.llvm.org/docs/ControlFlowIntegrity.html#indirect-function-call-checking

However, the analyzer does not have enough information to check
cross-dso calls. In these instances, CFI crashes upon calling the
function with an error like:

pthread_create_linux.cc:60:16: runtime error:
control flow integrity check for type
'int (unsigned long *, const pthread_attr_t *, void *(*)(void *), void *)'
failed during indirect function call
(/lib/x86_64-linux-gnu/libpthread.so.0+0x9200):
note: (unknown) defined here pthread_create_linux.cc:60:16:
note: check failed in crashpad_handler,
destination function located in /lib/x86_64-linux-gnu/libpthread.so.0
