[PATCH v3 3/5] external-arm-toolchain: check for TCLIBC being glibc

["Denys Dmytriyenko" <denis@denix.org>]

From: Denys Dmytriyenko <denys@ti.com>

The old TARGET_OS check doesn't work, as it only checks for uclibc and musl at
the end, while TARGET_OS is usually "linux-musleabi", uclibc has been deprecated
and new options like "newlib" and "baremetal" were added. Plus it only works for
the target, but not SDK. Switch to simply checking for TCLIBC = glibc.
