A recipe needs to be created for the test suite due to the dependency chain between libgcc -> glibc -> libgcc-initial, and the requirements of the test suite to have libgcc for compilation and execution. The glibc test suite does not use dejagnu like the gcc test suites do. Instead a test wrapper script is used along with the assumed dependency of having the same filesystem available on build host and target. For qemu linux-user the same filesystem is inherently available, for remote targets NFS is used. Separate test wrapper scripts are created for qemu linux-user or ssh targets, with the same TOOLCHAIN_TEST_* variables used for configuration.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
