Problem and solution
However, there will be some errors when installing gcc@4.8.5, like

san/asan_linux.cc:95:20: error: 'SIGSEGV' was not declared in this scope
Then, I google it and find a solution here issue on spack-github
First, there need several patchs: gcc-backport.patch, ucontext_t-4.8.patch, signal.patch, stack_t-4.8.patch. Some (gcc-backport.patch and signal.patch) are already exist in spack (.../var/spack/repos/builtin/packages/gcc), and the other need to be download from other place.ucontext_t-4.8.patch and
stack_t-4.8.patch.
Then, these three lines need to be added the package.py file, located in .../var/spack/repos/builtin/packages/gcc

patch('ucontext_t-4.8.patch', when='@4.8')
patch('signal.patch', when='@4.8')
patch('stack_t-4.8.patch', when='@4.8')
Finally, I install gcc@4.8.5 successfully using gcc@7.5.0 with low version texinfo and gmp, also with LD_PRELOAD=/usr/lib/gcc/x86_64-pc-linux-gnu/11.2.1/libstdc++.so.6.
