rework architecture / embedded systems concept

Make configuration of new targets cheap.
Just add a new file in target/arch/sys-enabled/foo.
See other files for syntax. While doing runtime tests
with the new infrastructure I've updated a lot of other
stuff:
- gcc 4.5.2
- uClibc 0.9.32-rc1 (NPTL)
- strongswan, php, miredo, parted, util-linux-ng, e2fsprogs

I promise, this is the last big fat commit this year ;)

++ * Core file format: The core file is written in such a way that gdb
++ * can understand it and provide useful information to the user (under
++ * linux we use the `trad-core' bfd).  The file contents are as follows:
++ *
++ *  upage: 1 page consisting of a user struct that tells gdb
++ *	what is present in the file.  Directly after this is a
++ *	copy of the task_struct, which is currently not used by gdb,
++ *	but it may come in handy at some point.  All of the registers
++ *	are stored as part of the upage.  The upage should always be
++ *	only one page long.
++ *  data: The data segment follows next.  We use current->end_text to
++ *	current->brk to pick up all of the user variables, plus any memory
++ *	that may have been sbrk'ed.  No attempt is made to determine if a
++ *	page is demand-zero or if a page is totally unused, we just cover
++ *	the entire range.  All of the addresses are rounded in such a way
++ *	that an integral number of pages is written.
++ *  stack: We need the stack information in order to get a meaningful
++ *	backtrace.  We need to write the data from usp to
++ *	current->start_stack, so we round each of these in order to be able
++ *	to write an integer number of pages.

-	Taken from OpenWrt, this patch fixes for a broken daemon() function
-	in applications linked against pthread, as the fork() function provided
-	by pthread has to be used then. It is said, that this won't fix for
