Committed: libgloss/cris/linunistd.h Don't override reentrant-errno for syscalls.

[Hans-Peter Nilsson]

Noticed by inconsistent errno returns from the Linux syscalls in
the to-be-committed "sim"-testsuite using newlib.  I blame
copy-paste; I thought something picked up this errno and put it
in the newlib _REENT-structure, but that's apparently wrong.

	* cris/linunistd.h: Don't redefine errno as extern int.
