Currently, when verifying the configuration of a uClibc toolchain for
the presence of locale support, we check __UCLIBC_HAS_LOCALE__. It
turns out that we in fact also expect __UCLIBC_HAS_XLOCALE__ to be
defined, as without it locale_t is not defined, causing build failure
in some packages, such as libcpprestsdk:

As essentially our requirement for uClibc in external toolchains is
"it should match the uClibc configuration used by Buildroot for
internal toolchains", it makes sense to verify
__UCLIBC_HAS_XLOCALE__. Note that of course checking
__UCLIBC_HAS_XLOCALE__ is sufficient, as it cannot be enabled if
__UCLIBC_HAS_LOCALE isn't.
This addresses an issue with the Synopsys ARC external toolchain,
which is built with __UCLIBC_HAS_LOCALE__, but without
__UCLIBC_HAS_XLOCALE__ causing a build failure with some
packages (such as libcpprestsdk).
Therefore, this patch also changes how the Synospys ARC external
toolchain is exposed in Buildroot: it no longer advertise locale
support.
