Hi Christer,
thankyou very much for your help. I have tested your changes:
For binutils 2.26:
$ configure --prefix=/opt/rpi --with-sysroot=/opt/rpi/sysroot
--disable.nls --target=arm-linux-gnueabihf --disable-multilib
$ make
$ make install
For stage 1 of gcc 7.2.0:
$ configure --prefix=/opt/rpi --target=arm-linux-gnueabihf
--enable-languages=c --without-headers --disable-nls
--disable-multilib --disable-threads --disable-shared
$ make all-gcc all-target-libgcc
$ make install-gcc install-target-libgcc
For linux kernel headers (following your suggestion):
$ cd linux
$ make headers_install ARCH=arm INSTALL_HDR_PATH=/opt/rpi/sysroot
For glibc 2.29 (following your suggestion):
$ configure --prefix=/usr --host=arm-linux-gnueabihf
--with-headers=/opt/rpi/sysroot/include --disable-multilib
$ make
$ make install DESTDIR=/opt/rpi/sysroot
Until this point everyting ok (I realized that now /opt/rpi/sysroot is
populated with /usr and the rest of standard folders and with include
files). The problem arises when compiling stage 2 of gcc using the
modifications you suggested (I use separated build folders for stages
1 and 2):
$ configure --prefix=/opt/rpi --target=arm-linux-gnueabihf
--enable-languages=c,c++ --disable-nls --disable-multilib
--with-sysroot=/opt/rpi/sysroot
$ make
The process terminates with the following output:

Any idea or suggestion?
Yes. Don't listen to me ;-)
The kernel headers should go to sysroot/usr(include) not sysroot/(include)
You can just move the ones in sysroot/include to sysroot/usr/include and
you should be good to go.
