This patch does some initial cleanup, following the move to 2.6.32
minimum kernel version, by removing __LINUX_KERNEL_VERSION
conditionals that are now always-true or always-false. In the case of
__ASSUME_ARG_MAX_STACK_BASED, where the conditional used a kernel
version that was itself in a macro, the associated sysconf.c code is
also cleaned up and __ASSUME_ARG_MAX_STACK_BASED removed completely.
Tested x86_64 that disassembly of installed shared libraries is
unchanged by the patch.

Bug Fixes:
* nss/nsswitch.c (_res): Remove redundant variable definition.
The real one is in resolve/res_init.c, and having both prevents
using -fno-common when building the shared library.
* sunrpc/rpc_prot.c (_null_auth): Same. Original is in rpc_common.c.
* sysdeps/unix/sysv/linux/alpha/brk.S: When PIC, define __curbrk as
a .bss object not a COMMON symbol.
* sysdeps/alpha/bsd-_setjmp.S, sysdeps/alpha/bsd-setjmp.S: Must load
$gp before referencing __sigsetjmp symbol. Retain LITUSE for same.
Optimizations:
* sysdeps/alpha/strlen.S: Rearrange first-word setup and thense the
main loop for better dual-issue on EV5. Rearrange binary search to
pipeline better and trim one instruction.
Cosmetic Changes:
* time/localtime.c (localtime_r): Move lock declaration back next to
the comment where it was before the 960724 change.
* INSTALL, manual/maint.texi: alpha-gnu-linux -> alpha-ANYTHING-linux.
The second word is supposed to be the hardware manufacturer.
* sysdeps/alpha/_mcount.S: Retain LITUSE for __mcount.
* sysdeps/alpha/setjmp.S: Retain LITUSE for __sigsetjmp_aux.
* sysdeps/alpha/divrem.h: More local labels, retain LITUSE for _mcount.
* sysdeps/alpha/alphaev5/add_n.S, sysdeps/alpha/alphaev5/lshift.S,
sysdeps/alpha/alphaev5/rshift.S, sysdeps/alpha/alphaev5/sub_n.S:
Same cleanups as with EV4 GMP stuff.

* sysdeps/generic/stpncpy.c (__stpncpy): Fix so it works without
segfault when called with an N that is not a multiple of four and
src[N-1]=='\0'.
* misc/syslog.c (LogType): New variable.
(openlog): If connect() with SOCK_DGRAM fails with EPROTOTYPE,
try again with SOCK_STREAM (the Linux syslogd uses a socket of the
latter type).
(vsyslog): When LogType==SOCK_STREAM, also send ASCII NUL
terminator as a record-delimiter. If __send(LogFile) fails,
call closelog() so logfile gets re-opened next time.

of Makeconfig.
[$(cross-compiling)=no]: Change test before making librpcsvc
