Thanks for your explanation.
If build=host=target, this is a "native compiler".
You typically configure this by specifying none of --build=, --host=,
or --target= .
If build=host but not equal to the target, it is a cross-compiler. You
usually configure with just a suitable --target= , and not more.
I tried again setting --host=x86_64-linux-gnu --build=x86_64-linux-gnu
--target=arm-linux-gnueabihf --disable-multilib
--with-sysroot=/usr/arm-linux-gnueabihf
--with-native-system-header-dir=/include and I got the following output:
/usr/bin/arm-linux-gnueabihf-ld: cannot find
/usr/arm-linux-gnueabihf/lib/libc.so.6 inside /usr/arm-linux-gnueabihf

The path is in the SEARCH_DIR:
SEARCH_DIR("=/usr/local/lib/arm-linux-gnueabihf");
SEARCH_DIR("=/lib/arm-linux-gnueabihf");
SEARCH_DIR("=/usr/lib/arm-linux-gnueabihf");
SEARCH_DIR("=/usr/local/lib"); SEARCH_DIR("=/lib");
SEARCH_DIR("=/usr/lib"); SEARCH_DIR("=/usr/arm-linux-gnueabihf/lib");
I tried to see if the files are in the directory and they are:
-rwxr-xr-x 1 root root 126500 Jan 15 2023 ld-linux-armhf.so.3
-rwxr-xr-x 1 root root 1102644 Jan 15 2023 libc.so.6
-rw-r--r-- 1 root root 8862 Jan 15 2023 libc_nonshared.a
Maybe one of the options is not correct

This looks like some Debian-style arrangement where
"--with-sysroot=$SYSROOT" is not necessary - all the $target stuff is
already in some
absolute place on the host, not "sysrooted" in some user-chosen place
like "/opt/host-$target" which I myself have use. Furthermore the
glibc install packages use symlinks to absolute addresses, not to
"../../lib" from the "/usr/lib". I have always fixed these symlinks when
using
prebuilt glibc packages from Debian distros in a $SYSROOT.
