A note: there is a recent change to ELF interpreter path in this doc. 
This patch series use the new ELF interpreter path.  If you want to test
the patches natively (on a LoongArch system or via a emulator), create a
compatibility symlink before building GCC with the patches:

ln -sv ld.so.1 /lib64/ld-linux-loongarch-lp64d.so.1
