Richard Kistruck 7ad16fa35c Mps br/vc9: mpstd.h: (for all remaining platforms) 
- fix broken behaviour if CONFIG_PF_* is set (result depends on 
  order of the various platform elifs!); change it to always use 
  platform detection by looking at preprocessor symbols, and 
  then (if CONFIG_PF_STRING *and* CONFIG_PF_* are set) check 
  that CONFIG and detection match;
xcppgc.gmk: define both CONFIG_PF_STRING and CONFIG_PF_*.

/* 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_*:

* 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.
