remove deprecated architectures v850/i960
Both architectures are more or less deprecated. No Linux upstream support, no gcc support for uClinux.

-Overview
----------------------------------------------------------------------------
-
-This is the README file for the i960 support in uClibc.
-
-This has been tested with gcc 2.95.3 and i960-intel-coff target.
-
-There is no support at all to compile with the intel CTOOLS, as this would
-have required too many changes to uClibc. So you won't see any support
-in the asm files for position independent data or code.
-
-Quirks needed
----------------------------------------------------------------------------
-
-prepended underscore
---------------------
-
-As the i960 compiler prepends an underscore to symbols, it is critical that
-Rules.mak defines SYMBOL_PREFIX as _, such that -D__UCLIBC_UNDERSCORES__
-is added to CFLAGS to make sure that underscores are applied to symbol
-names when needed.
-
-
-__va_copy in va-i960.h
-----------------------
-
-When compiled with gcc-2.95, the __va_copy macro in va-i960.h seems to be broken
-and it has to be modified in order for uClibc to compile correctly.
-
-Change:
-
-#define __va_copy(dest, src) (dest) = (src)
-
-To:
-
-#define __va_copy(dest, src) dest[0] = src[0]; dest[1] = src[1]
-
-
-gcc integration
----------------------------------------------------------------------------
-
-I've preferred modifying the specs file so that the i960-intel-coff compiler
-directly compiles with uClibc.
-
-First, compile and install the standard i960-intel-coff compiler, which is meant
-to be used with newlib.
-
-Then, compile uClibc, installing over the newlib include files and libraries.
-
-Update the specs file with the included specs.uclinux.gcc-2.95.i960-intel-coff
-
-This specs file always build relocatable objects, which has the disadvantage
-of not letting you know if the link is missing any symbols.
-
-coff2flt
----------------------------------------------------------------------------
-
-In order to run the executables under uClinux, fully relocatable binaries
-need to be built using coff2flt.
-
-We have built a working coff2flt that works with the i960 and the current version
-of binfmt_flat with uClinux.
-
-Contact Martin Proulx <mproulx at okiok.com> for further informations.
