This diff patches out mono's use of syscall(SYS_fork), which is the
only instance of syscall(2) in use. Upstream has this behind:
#elif !defined(HOST_DARWIN) && defined(SYS_fork)
This diff changes that to #elif defined(__linux__)... and as a
consequence, fork(2) is simply used.
With this patched, none of the mono binaries I looked at (mono,
mono-sgen, monodis) or shared objects have any reference to syscall(2)
anymore.
ok?
