	  Enables --sysroot=dir for binutils and gcc.
	  Use dir as the logical root directory for headers and libraries.
	  For example, if the compiler would normally search for headers in
	  /usr/include and libraries in /usr/lib, it will instead search
	  dir/usr/include and dir/usr/lib.

	  This does not work with gcc < 4.2.0 (4.1.2 gets
	  ORIGINAL_AS_FOR_TARGET wrong)

	  For some platforms, proper stack unwinding works perfectly,
