Add a _REENT_ERRNO() macro to encapsulate the access to the
_errno member of struct reent. This will help to replace the
structure member with a thread-local storage object in a follow
up patch.
Replace uses of __errno_r() with _REENT_ERRNO(). Keep __errno_r() macro for
potential users outside of Newlib.
* libc/machine/powerpc/fix64.h: Fix typo for _simdldcheck
prototype.
* libc/machine/powerpc/simdldtoa.c: Remove prototype for
_simdldcheck(). Also add unsigned cast for index variable in
for loop using sizeof operators.
* libc/machine/powerpc/strtoufix32.c: Remove unused variable.
* libc/machine/powerpc/strtosfix64.c: Fix call to _simdldcheck.
* libc/machine/powerpc/strtoufix64.c (_strtoufix64_r): Ditto
plus fix shift calculation for determining if there is a
carry from word2.
