On Ubuntu 21.10 (ppc64le) building `raid6test` with gcc (Ubuntu
11.2.0-7ubuntu2) 11.2.0 fails with the error below.
gcc -I.. -I ../../../include -g -O2 -I../../../arch/powerpc/include -DCONFIG_ALTIVEC -c -o vpermxor1.o vpermxor1.c
vpermxor1.c: In function ‘raid6_vpermxor1_gen_syndrome_real’:
vpermxor1.c:64:29: error: expected string literal before ‘VPERMXOR’
64 | asm(VPERMXOR(%0,%1,%2,%3):"=v"(wq0):"v"(gf_high), "v"(gf_low), "v"(wq0));
| ^~~~~~~~
make: *** [Makefile:58: vpermxor1.o] Error 1
So, include the header `asm/ppc-opcode.h` defining this macro also when
not building the Linux kernel but only this too.
