[PATCH 05/29] Allow fd_mask type not be an array of long.

[Andrew Pinski]

Even though XPG4.2 requires fd_set member be a long, AARCH64:ILP32
needs it to be the same size as AARCH64:LP64 for big-endian so we
need it to be long long.

* misc/sys/select.h (__FD_MASK_TYPE): Define.
(__FD_MASK_CONST): Define.
(__fd_mask): Change to base on __FD_MASK_TYPE.
(__FD_MASK): Use __FD_MASK_CONST.
