* misc/sys/select.h (__FD_MASK): Renamed from __FDMASK.
(__FD_ELT): Renamed from __FDELT.
* misc/bits/select2.h (__FD_ELT): Likewise.
* bits/select.h (__FD_SET, __FD_CLR, __FD_ISSET): Use __FD_ELT,
__FD_MASK instead of __FDELT, __FDMASK.
* sysdeps/i386/bits/select.h (__FD_SET, __FD_CLR, __FD_ISSET):
Likewise.
* sysdeps/x86_64/bits/select.h (__FD_SET, __FD_CLR, __FD_ISSET):
Likewise.
* elf/Makefile (gen-ldd): Fix pattern.
* elf/rtld.c (dl_main): Only use USE___THREAD when defined.
