[arm] Remove obsolete FPA support (1/n): obsolete target removal

[Richard Earnshaw <rearnsha at arm dot com>]

This patch is the first of a series to remove support for the now
obsolete FPA and Maverick co-processors.

This patch removes those targets and configuration options that were
marked as deprecated in GCC-4.7 and removes the config fragments that
depended on them.

	* config.gcc (unsupported): Move obsoleted FPA-based configurations
	here from ...
	(obsolete): ... here.
	(arm*-*-freebsd*): Remove.
	(arm*-*-linux*): Only accept EABI variants.  Simplify logic.
	(arm*-*-uclinux*): Likewise.
	(arm*-*-ecos-elf): Remove.
	(arm*-*-rtems*): Remove.
	(arm*-*-elf): Remove.
	(arm*-wince-pe*): Remove.
	(arm, --with-fpu): Remove support for fpa and Maverick variants.
	* arm/ecos-elf.h: Delete.
	* arm/t-strongarm-elf: Delete.
	* arm/rtems-elf.h: Delete.
	* arm/wince-pe.h: Delete.
	* arm/pe.c: Delete.
	* arm/pe.h: Delete.
	* arm/t-wince-pe: Delete.

Tested by building the following variants:

Deleted builds (confirmed that configuration of gcc fails):

arm-elf
arm-linux

Remaining builds (confirmed that a cc1 is still built):

arm-linux-gnueabi
arm-vxworks
arm-netbsdelf
arm-rtemseabi
arm-symbianelf

R.
