Thank you very much! I'm trying it now. I don't know the history of the change: https://github.com/oracle/solaris-userland/blob/master/components/gcc10/patches/001-multilib-sparc.patch It has following comment: # We want sparc/i386 to match locations for their 32 bit support when building # multilib. For now use the more generic /32. This has not been filed # upstream. I wonder whether it makes sense to have it in upstream?
