[Erik M. <er...@us...>]

Update of /cvsroot/blob/blob/src/blob
In directory usw-pr-cvs1:/tmp/cvs-serv12890

Modified Files:
	Makefile.am rest-ld-script.in 
Removed Files:
	stack.S 
Log Message:
Fix bug with new GNU linkers outputting the .bss section.

Old GNU linkers let the section attributes of the output section take
precedence over the input section attributes, new GNU linkers do it the
other way around. The .bss section only needs to be allocated, but if
you put a .stack section in it that is CONTENTS+(whatever), the new
linkers will promote the output .bss section to CONTENTS+(whatever) and
hence the output section won't be discarded.

This patch fixes it by directly allocating the necessary stack space
in the linker script.
