LLAMA_BUILD_SERVER=1 make command execution error

[stoneLee81]

I execute the LLAMA_BUILD_SERVER=1 make command in the root directory of the llama.cpp project， But compilation fails with below error

I llama.cpp build info:
I UNAME_S: Darwin

make: *** No rule to make target private', needed by server'. Stop.

I don't know what went wrong, causing the failure

os: Ventura 13.4.1 m1max
gcc: Apple clang version 14.0.3 (clang-1403.0.22.14.1)

try to install gmake via brew, or use the cmake project

It's caused by Apple using a very old GNU Make version.

@Green-Sky, I planned to fix this, I will make a quick PR, alright?
