Re: ld needing libgcc

>What should __end__ be assigned to (end of what?, data, text, bss)?

The end of the BSS I think.  The arm-coff linker does define this but the ELF 
one doesn't.  I've appended below a linker patch to add this symbol for the 
ARM/ELF scripts.  Nick, does this seem right to you?  An alternative would be 
to add it to elf.sc, or to fix newlib to not use this symbol in the first 
place.

>Also which is the ldscripts that is used (or when is it called):

Depends on the linker options you use.  The .x version will be called for most 
"normal" situations.  I think the -v option will tell you what script is in 
use.

	* emulparams/armelf.sh (OTHER_BSS_SYMBOLS): Add __end__.
	* emulparams/armelf_linux.sh: Likewise.
	* emulparams/armelf_linux26.sh: Likewise.
