Bug description

I am running the recently released OS X command line tools which contain Apple Clang 5.1. The flag `-f-no-defer-pop' is rejected by this version of clang. This makes it impossible to use ocamlc or ocamlopt to compile .c stubs.

Steps to reproduce

Write "int main(void) { return 0; }" into a file `test.c' and do 'ocamlc -c test.c'. You should get the error

clang: error: unknown argument: '-fno-defer-pop' [-Wunused-command-line-argument-hard-error-in-future]
clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

Additional information

My precise clang version is

Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.1.0
Thread model: posix
