Adding both the required toolchain options (libgcc) and baseline BSP definitions for arc support. Author: Alexey Brodkin <alexey.brodkin@synopsys.com> Date: Fri Feb 8 18:32:21 2019 +0300 linux-yocto: Add dependency on libgcc for ARC As of now in case of ARC there's no in-kernel implementation of basic libgcc functions used for millicode, multiplication, division etc instead we simply link with libgcc.a which provides everything used by the compiler.

This commit adds support of 1 simulated board (nSIM) and the mast affordable and powerful to date development board (HSDK). Once Qemu port for ARC is functional (it's being actively developed now) we'll switch from nSIM to Qemu. Still it would be really good to keep nSIM support in linux-yocto for now as it allows for simpler testing as compared to real HW.

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.
