GCC 16 introduced -flink-libatomic which automatically injects
-latomic_asneeded into link commands via LINK_LIBATOMIC_SPEC.
When glibc is built with a GCC 16 cross-compiler, the compiler
would attempt to link against libatomic which does not exist yet
at this stage.(libatomic is built later as part of gcc-runtime)

Hi Khem,
Updated this to use the toolchain-gcc override:
TARGET_CC_ARCH:toolchain-gcc += "-fno-link-libatomic"
SDK_CC_ARCH:toolchain-gcc += "-fno-link-libatomic"
Will be sending the fix in the coming series.
