So, how does one biulding all parts of gcc with "-O -g"?
In my shell script, I have
CFLAGS="-O -g"
export CFLAGS
CXXFLAGS="-O -g"
export CXXFLAGS
BOOT_CFLAGS="-O -g"
export BOOT_CFLAGS
../gcc/configure --prefix=$HOME/work --enable-languages=c,c++,fortran \
--enable-bootstrap --disable-libssp --disable-multilib
but during bootstrap I see

Note the "-g -O2". Why?
In addition to CFLAGS and BOOT_CFLAGS, you are missing CFLAGS_FOR_TARGET
(plus the same 3 for CXX). I don't know if that's still sufficient, but
that's what I used to set a few years ago.
