v7-a or v8-a library missing after rebuilding arm-none-eabi-gcc10

Hello Sir(s),

I had followed the document, How-to-build-toolchain.pdf, to rebuild the arm-none-eabi-gcc 10 (q4-major) for fixing CMSE check fail issue. However, there are some library missing(v7-a or v8-a relevant libraries) comparing with official arm-none-eabi-gcc 10.

I had checked the build scripts, but I cannot figure out why...

Could you help me? or give me some hints about the problem. Thank you very much.

Best regards!
