patch that moves PTR_MANGLE for alpha

I'm running into the same problem. My host is x86_64-unknown-linux-gnu and my
target is alphaev56-unknown-linux-gnu.

I'm attaching a patch that moves PTR_MANGLE from sysdeps/unix/alpha/sysdep.h
into sysdeps/unix/sysv/linux/alpha/sysdep.h just for consistancies sake.
PTR_MANGLE was inside of a ifdef __ASSEMBLER__ in sysdeps/unix/alpha/sysdep.h.
Moving it below the #endif /* ASSEMBLER */ in sysdeps/unix/alpha/sysdep.h has
the same result of putting it in the bottom of
sysdeps/unix/sysv/linux/alpha/sysdep.h. Which is where it exists in the rest of
the architectures.

Also, in every architecture besides alpha, the #if defined NOT_IN_libc &&
defined IS_IN_rtld contition has #else. alpha has a #elif defined PIC. The
attached patch changes that #elif defined PIC to a #else.

With these changes I no longer get undefined references to PTR_MANGLE and
PTR_DEMANGLE. This is what I'm now seeing.
