Compiled compiler missing dsp library, failing to compile fft and dsp related programs

[cjkzwe]

Description: After successfully compiling the compiler, I attempted to compile some programs that rely on the dsp library, such as fft. However, it appears that the compiled compiler is missing the dsp and some other libraries, resulting in failed compilation.
