Possible indeed. There are newer versions of the ARC toolchain
available at
https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases,
but I checked the latest and it still has xlocale disabled.

One option is to ask the ARC/Synopsys people to enable XLOCALE in their
uClibc configuration.

Another option is to drop the ARC/Synopsys toolchain entirely.

A third option is to change the check done by Buildroot to verify
__UCLIBC_HAS_XLOCALE__ instead of __UCLIBC_HAS_LOCALE__. This way it
will be valid to say that the ARC toolchain does not have locale
support.
