gcconfig.h (sparc-linux): Use LINUX_STACKBOTTOM.

Browse source 
2005-04-17  David S. Miller  <davem@davemloft.net>

	* include/private/gcconfig.h (sparc-linux): Use LINUX_STACKBOTTOM.
	* os_dep.c (GC_linux_stack_base): Check for bug present in some
	Sparc glibc variants where __libc_stack_end is erroneously set
	to "1".  Fallback to procfs code in that case.
