Well not sure why there's a dependency on glibc as w/o ARC target support
in dpkg nothing could be built for ARC. For example I did built Binutils
with fixed dpkg.

Above 2 are not [yet] supported but seems to be easy ones.

Not sure about "libxcrypt" (whatver that means), but libgpg-error supports ARC since 2018, see:

Done in 2019, see https://hg.mozilla.org/projects/nspr/rev/cc73b6c7dab2e8053533e1f2c0c23dc721e10b76

Not sure what needs to be done here as I know we build a lot of complex
things with OpenEmbedded/Yocto and openssl libs are being built for sure.

See above, quite some do work.
