Hello,

+Synopsys/ARC people in Cc.

config BR2_PACKAGE_UCLIBC_ARCH_SUPPORTS
        bool
        default y if BR2_aarch64
        default y if BR2_aarch64_be
        default y if BR2_arcle
        default y if BR2_arceb

so I'd say no we don't need to drop support for big endian ARC as
uClibc still supports it.

However, I must say we have quite a few ARC-specific issues, which I
have reported a while ago to the Synopsys people, and there's no longer
any Synopsys participation to Buildroot. So I'm thinking we should
probably take this as a "Synopsys no longer cares" and therefore we
should drop support for ARC.

Let's see if they react to this e-mail. If they don't, it will be a
clear signal that they don't care anymore, and we should drop ARC.
