I have here gcc 10 and the output is:
|  CC      arch/arc/kernel/signal.o
|arch/arc/include/asm/bitops.h: Assembler messages:
|arch/arc/include/asm/bitops.h:236: Error: junk at end of line, first unrecognized character is `0'
|arch/arc/include/asm/bitops.h:236: Error: junk at end of line, first unrecognized character is `0'
|make[3]: *** [scripts/Makefile.build:283: arch/arc/kernel/signal.o] Error 1
|make[2]: *** [scripts/Makefile.build:500: arch/arc/kernel] Error 2
|make[1]: *** [Makefile:1788: arch/arc] Error 2

the reason is that:
| #ifndef CONFIG_ARC_PLAT_EZNPS
| BIT_OPS(set, |, bset)
| BIT_OPS(clear, & ~, bclr)
| BIT_OPS(change, ^, bxor)
| #else
| BIT_OPS(set, |, CTOP_INST_AOR_DI_R2_R2_R3)
| BIT_OPS(clear, & ~, CTOP_INST_AAND_DI_R2_R2_R3)
| BIT_OPS(change, ^, CTOP_INST_AXOR_DI_R2_R2_R3)
| #endif

and the config supplied does not accept CTOP_INST_AAND_DI_R2_R2_R3
(which is
	#define CTOP_INST_AAND_DI_R2_R2_R3              0x4A664C04
)
and the assembler does not like that.
After the removal CONFIG_ARC_PLAT_EZNPS I got to stage 2:
|drivers/irqchip/irq-eznps.c:80:16: error: 'CTOP_AUX_IACK' undeclared (first use in this function)
|   80 |  write_aux_reg(CTOP_AUX_IACK, 1 << irq);

so I removed CONFIG_EZNPS_GIC. And then I ended with:
|  LD      vmlinux.o
|arc-linux-ld: gcc-10.1.0-nolibc/arc-linux/bin/../lib/gcc/arc-linux/10.1.0/arc700/libgcc.a(_muldi3.o): compiled for a little endian system and target is big endian
|arc-linux-ld: failed to merge target specific data of file gcc-10.1.0-nolibc/arc-linux/bin/../lib/gcc/arc-linux/10.1.0/arc700/libgcc.a(_muldi3.o)

Please update CI and ARC.
