Not having gcc is about as good for security as ROT13 encoding the
names of all executables. Sure, it will confuse every script that
tries to install something, but is it worth it?
If you still have doubts, you can install gcc for compiling the kernel
and then remove it afterwards. Cross-compiling is experimental at
best, if it works at all. I would certainly not try the result of the
cross-compilation on a production server :-).
