[patch/rfc] Rationalize Instruction Set Architecture targets

[patch/rfc] Rationalize Instruction Set Architecture targets

[Andrew Cagney]

[-- Attachment #1: Type: text/plain, Size: 657 bytes --]

Hello,

The attached patch is to follow on the previous MAINTAINERS file patch 
which gave the impression of removing djgpp from the target list :-(

This patch:

- changes the target/architecture  section to the more exact ``Target 
Instruction Set Architecture''.

- where possible changes from an OS specific to a generic target

- where that fails, a more correct and active, cross unix target

I'm not sure how to follow this through.  I could commit it all as is, 
or incrementally has maintainers for specific targets (eg PPC/rs6000, 
i386) give an ok.

It does reduce the number of build targets significantly which is a good 
thing.

enjoy,
Andrew
