[PATCH] pru: Do not define MISSING_SYSCALL_NAMES for pru

The PRU newlib port is supposed to implement case #2 as described in
newlib/libc/include/reent.h .  Thus drop the defining of
MISSING_SYSCALL_NAMES.

Before:
  $ pru-nm libnosys.a | grep getentropy
  00000000 T getentropy

With this patch:
  $ pru-nm libnosys.a | grep getentropy
  00000000 T _getentropy

Ok for master?

ChangeLog:

	* libgloss/configure: Regenerate.
	* libgloss/libnosys/acinclude.m4: Do not define
	MISSING_SYSCALL_NAMES for pru.
