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.
