Now that the common syscall implementation supports vararg calling
conventions we can safely use it on OpenRISC.
This saves a bit of code in the openrisc implementation.

Busybox internally calls syscall(2).
- in unistd.h defined something like
int syscall(nr, ....)
- in syscall.c (common) implemented as
int syscall(nr, arg1, arg3, arg3, arg4, arg5, arg6)
This will not work, busybox thinks syscall should have varargs calling
conventions. But it doesnt in the uclibc implementation so no args go through.
Most architectures this will work. But on openrisc varargs are all sent on the
stack. Regular args are passed in registers.

Previously we saved everything, but we only need to save the registers
that are promised to be untouched by the setjmp call.

Sync with GNU C library. Found while trying to compile
linux-rdma to uClibc-ng.

License notices in most of the source files refer to an outdated
FSF address. Replace it with URL, like in the rest of the source

Only alpha, hppa and sparc need non-default value.

.globl can be used for every architecture so remove the define.
Sync with GNU C library.

It's even no longer required for non-ported ppc64
architecture. Sync with GNU C library.
This simplify the macros in include/libc-symbols.h.
