Richard Brooksby f2f702fc18 Added single compilation unit version of mps library to allow global optimization and universal binary building. minor fixes to other sources to avoid clashing symbols. 
Separated XCI3GC (gcc) from XCI3LL (clang) platforms, so that we can build both 32- and 64-bit binaries with clang.
Enabled universal (multi architecture) builds.

/* DESIGN NOTES
* ------------
* [These should be moved to a proper buildsys design doc. RHSK]
*
* mpstd.h does two main things:
* 1. platform detection by looking at preprocessor symbols;
* 2. setting variables (eg. MPS_PF_STRING, MPS_WORD_WIDTH).
*
* Sometimes the platform is *already* known by the buildsystem:
* - the Global Graphics buildsystem always sets CONFIG_PF_*.
* - the Ravenbrook buildsystem knows the platform and may (but
* typically does not) set CONFIG_PF_*.
*
* Regardless of this, mpstd.h still attempts to detect the platform.
* (This is intentional). However if both CONFIG_PF_* and
* CONFIG_PF_STRING are set, then mpstd.h performs a third function:
* 3. checking that the detected platform corresponds to that
* specified by CONFIG_PF_*.
*
* Sometimes no MPS buildsystem is in use, so the platform *must*
* be detected. For example, when client software #includes mps.h,
* we want it to just work out of the box with whatever compiler is
* being used. In other words we do not require the client to define
* CONFIG_PF_*.
* (This is the case that justifes mpstd.h doing platform detection
* by looking at preprocessor symbols; otherwise we'd simply use
* CONFIG_PF_*).
*
* mpstd.h fails if it cannot detect the platform (even if CONFIG_PF_*
* is specified). This is intentional. mpstd.h does *not* allow
* CONFIG_PF_* to override the platform as detected from preprocessor
* symbols. This is intentional.
*
* References:
* GG buildsys use of CONFIG_PF_*:
* <http://info.ravenbrook.com/mail/2005/03/01/15-45-17/0.txt>

* os.i5), as we have to support Irix 5.2, which doesn't define it. We
* check the value of _MIPS_FPSET, as it is defined across all Irix 5
* and 6 platforms, and on Irix 6 distinguishes O32 from the other two
* ABIs. When we support the other ABIs, we need a new OS name for
* them. Alignment from testing.
