I'm trying to build glibc on cygwin but I keep on getting this error

    [ALL  ]      rtld-Rules:40: *** This makefile is a subroutine of
elf/Makefile not to be used directly.  Stop.
    [ALL  ]      make[4]: Leaving directory '/build/src/glibc-2.38/elf'
    [ERROR]      make[3]: *** [Makefile:1315:

    [ALL  ]      make[3]: Leaving directory '/build/src/glibc-2.38/elf'

I'm building it through crossingtool-ng.

Here's the configuration it used:

    /build/x86_64-pc-linux-gnu/src/glibc/configure --prefix=/usr
--build=x86_64-build_pc-cygwin --host=x86_64-pc-linux-gnu
--cache-file=/build/x86_64-pc-linux-gnu/build/build-libc/multilib/config.cache
--without-cvs --disable-profile --without-gd
--with-headers=/x-tools/}x86_64-pc-linux-gnu/x86_64-pc-linux-gnu/sysroot/usr/include
--disable-debug --disable-sanity-checks --enable-kernel=6.5.5
--with-__thread --with-tls --enable-shared --enable-add-ons=no

Cygwin it is not a supporter ABI. The glibc currently only supports Linux and Hurd.
