[klibc] s390: mmap: Change inline assembly to work with Clang
Clang rejects the operand "%b1" to svc:
usr/klibc/arch/s390/mmap.c:61:3: error: invalid operand in inline asm: ' svc ${1:b}'
Since svc always takes an immediate operand, the "b" modifier is not
needed. After deleting it, both Clang and gcc generate the correct
instruction "svc 90".
