erts: Do not use named no_cpuid label in asm
Ask compiler to generate unique label name. Using named label has implications
on optimizer, that may lead to the compilation errors as the following:
pthread/ethread.c: Assembler messages:
pthread/ethread.c:213: Error: symbol `no_cpuid' is already defined
pthread/ethread.c:213: Error: symbol `no_cpuid' is already defined
pthread/ethread.c:213: Error: symbol `no_cpuid' is already defined
