do not use fast call hacks

(instant patch for symlink)

on some platforms, fast call hacks are used in ioquake3 to yield some minor
performance gains. in r2282, i marked Clang/LLVM as a platform where these
hacks should not be used. this is required because of how Clang/LLVM-generated
code works by default. the hacks still work with GCC (on some platforms) by
default, but not when the stack protector feature is enabled.

btw, i suspect that the gains are imperceptible anyway. note: they are, for
example, turned off in Tremulous (an ioquake3-based mod) at all times.
