dumps error description

In short:
install -v -d mybuild && cd mybuild

../configure --prefix=3D/tools/gcc-12.2.0 --without-build-config LD=3Dld
--enable-libssp --enable-bootstrap --enable-lto --with-isl=3D/usr/local
--with-mpc=3D/usr/local --with-mpfr=3D/usr/local --with-gmp=3D/usr/local
--with-system-zlib --enable-threads=3Dposix --enable-__cxa_atexit
--enable-clocale=3Dgnu --enable-gcov
--enable-languages=3Dc,c++,fortran,objc,obj-c++,jit,go --enable-host-shared
--disable-multilib --enable-shared

after some time I have got error g++: fatal error: unknown spec function
=E2=80=98dumps=E2=80=99
compilation terminated. (file 1 attached)

I have found nothing about fixing 'dumps' err
After that I found at stackoverflow, that if to unset global variables, it =
can
help to continue
(https://stackoverflow.com/questions/75548412/without-unset-compiling-gcc-o=
n-crostini-fails-with-unknown-spec-function-dumps)

so I ran unset LIBRARY_PATH CPATH C_INCLUDE_PATH PKG_CONFIG_PATH
CPLUS_INCLUDE_PATH INCLUDE LD_LIBRARY_PATH
make

and compilation was going sufficient time, stage was completed
mybuild/config.log attached), but suddenly I have got error=20
configure:2630: error: in `/home/alexei/build/gcc-12.2.0/mybuild/intl':
configure:2632: error: C compiler cannot create executables
config.log from mybuild/intl attached also
very many variables in this file are empty

How to help compiler fine xgcc and continue?=
