From: WANG Xuerui <git@xxxxxxxxxx> In GCC, -G stands for "small data threshold", that instructs the compiler to put data smaller than the specified threshold in a dedicated "small data" section (called .sdata on LoongArch and several other arches). However, benefiting from this would require ABI cooperation, which is not the case for LoongArch; and current GCC behave the same whether -G0 (equal to disabling this optimization) is given or not. So, remove -G0 from CFLAGS altogether for one less thing to care about. This also benefits LLVM/Clang compatibility where the -G switch is not supported.
