I did so with gcc-10.2.0 and executed ./configure in the subdirectory
libstdc++-v3. The relevant part of config.log is this:
configure:16462: checking for ISO C99 support to TR1 in <fenv.h>
configure:16490: g++ -c -std=c++98 conftest.cpp >&5
configure:16490: $? = 0
configure:16497: result: yes
This is when trying to compile gcc-10.2.0 with gcc-10.2.0; so somehow
our bootstrapping process does something differently when creating the
final user facing gcc.
