Subject: [PATCH] Handle __cpu_mask usage

Fixes errors:

src/test/test-cpu-set-util.c:18:54: error: '__cpu_mask' undeclared (first use in this function)
src/test/test-sizeof.c:73:14: error: '__cpu_mask' undeclared (first use in this function)

__cpu_mask is an internal type of glibc's cpu_set implementation, not
part of the POSIX definition, which is problematic when building with
musl, which does not define a matching type.  From inspection of musl's
sched.h, however, it is clear that the corresponding type would be
unsigned long, which does match glibc's actual __CPU_MASK_TYPE.  So,
add a typedef to cpu-set-util.h defining __cpu_mask appropriately.

Upstream-Status: Inappropriate [musl specific]
