Alexey Brodkin 9cb6caf891 uclibc: ARC: Don't mess with CPU selection
Since uClibc-ng commit cde74b83f9b2 "ARC: remove special CFLAGS/LDFLAGS handling"
i.e. starting v1.0.23 CONFIG_ARC_CPU_xx options are not used.

Instead uClibc relies on toolchain defaults or build-system CFLAGS
for selection of ARC-specific code (i.e. distinguishes between
ARCompact and ARCv2 ISAs).

So we drop corresponding quirks from Buildroot as well.

help
Some people may wish to use their own modified uClibc
configuration file and will specify their config file
location with this option. See also docs/README in this
package. If unsure, use the default.

A space-separated list of configuration fragment files, that
will be merged to the main uClibc configuration file.

help
Enable this option if you want your toolchain to support
wide characters (i.e characters longer than 8 bits, needed
for locale support).

Enable this option if you want your toolchain to support
localization and internationalization.

Enabling this option will compile and install the getconf,
ldconfig and ldd uClibc utilities for the target.
You can save ~32 KiB in target space by disabling them since
they're normally not needed.
