building i386, gcc 5,6,7,8 misconfigures when our "as" redirects it to clang for assembly, following our hack in cctools to do that. the gcc build then fails.
I have not so far been able to overcome this other than: 1. deactivating all clangs 5+ prior to the build, to get the old gas or 2. defaulting gcc to use --with-as=/usr/bin/as Having the built gcc forever use /usr/bin/as as assembler would be awful, so option 1 looks better than 2. but ugh. I tried many things. gcc is complicated to build when you want it to do non-standard stuff. There may be some way to make it work...pls chime in...but I have likely tried it. passing in a specific ENV var to the stage1 compiler, or adding -Wa,-Q to the stage1 C and CXX flags, would probably be enough to fix it. Otherwise appears we will have to conflicts_build a bunch of clangs when building i386, which is a pain, esp if no buildbot to build it clean for us. Ken
