sandbox: errno: avoid conflict with libc's errno When building with LTO, the system libc's `errno` variable used in arch/sandbox/cpu/os.c conflicts with U-Boot's `errno` (defined in lib/errno.c) with the following error: .../ld: errno@@GLIBC_PRIVATE: TLS definition in /lib64/libc.so.6 section .tbss mismatches non-TLS reference in /tmp/u-boot.EQlEXz.ltrans0.ltrans.o To avoid this conflict use different asm label for this variable when CONFIG_SANDBOX is enabled.
