Unfortunately, I was unable to reproduce the problem mentioned in

Heres's a possible fix without testing. Please tell me if this works.

These are exported according to the LoongArch Toolchain Conventions[1]
as a replacement of the obsolete "_LOONGARCH_{ARCH,TUNE}" macros,
which are expanded to strings representing the actual architecture
and microarchitecture of the target.

The configure script and the GCC driver are updated so that
it is easier to customize and control GCC builds for targeting
different LoongArch implementations.

new configure options --with-simd={none,lsx,lasx};

This patch fixes libgccjit build failure on loongarch* targets,
