[OpenRISC] [RESEND PATCH 0/5] OpenRISC GCC Fixes for Glibc Support

[Stafford Horne <shorne@gmail.com>]

Hello,

Changes since v1:
 - Rebase

This just a resend of v1 with no changes from when I sent it last year.  I
hadn't committed it because I had not completed all testing in glibc.  Now that
I have done that and it all seems to work I will commit it.

I am currently working on the glibc port for OpenRISC.  This is a series of
patches that fix issues and add features that were missing in GCC causing glibc
testsuite failures.

Pretty much all of these changes are just adding macros.

These changes have been tested via the glibc test suite.
