I also confirm this. For the last two days I'm trying to install Gentoo from scratch on a new computer. I have "lto" in USE but my CFLAGS are more neutral (only native and O3). Gentoo hoses itself at about ~300 package out of ~400 on a emerge -e @world from stage 3. The error message is the same (checking build system type... Invalid configuration `x86_64-pc-linux-gnu': machine `x86_64-pc' not recognized) but during emerge of gettext.
OK, so how do I fix this? ~amd64 is can't be installed at the moment.

The failure might not be related to bash but to -flto in general. I suggest disabling flto at least for bash. We saw a similar bash miscompilation in https://gcc.gnu.org/PR88936 where -fipa-pta managed to break case matching code in bash. I suspect you see the same symptoms.

To clarify: the workaround is to drop -fipa-pta flag and rebuild at least bash. I don't think it's an LTO bug. Dropping from deps and renaming the bug.

There is something with readline definitely. You can downgrade readline to check that.

But check gcc manual:" -fipa-pta Perform interprocedural pointer analysis and interprocedural modification and reference analysis. This option can cause excessive memory and compile-time usage on large compilation units. It is not enabled by default at any optimization level." It is not enabled by default at any optimization level. Marek Bartosiewicz (comment#3 https://bugs.gentoo.org/675918#c3) says he have native lto and O3, and also experiencing same problems.
yes, disabling fipa-pta for bash-5.0 solves issue. updated @world with readline-8.0
If there are other issues with -O3 -match=native (without -fipa-pta) please file a new bug. We'll investigate there.
Fixed in =sys-devel/gcc-9.1.0.
