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.
You don't make it clear whether this is solely about building gcc itself,
or about building things *with* gcc.
The "forever" might just be "until there's a better solution", and it's
hard to see how option 2 would be more awful than creating yet another "X
can't build while Y is active" abomination.
