GC fix for sh-linux

[SUGIOKA Toshinobu]

Hi,

Java program built by gcj-3.4.4 always segmentation faults on sh-linux
kernel 2.6.x, glibc-2.3.4 nptl environment while GC initialization,
because it is accessing unallocated stack area.

Following patch fixes this problem, could someone apply it ?

	* include/private/gcconfig.h (sh-linux): Use LINUX_STACKBOTTOM.
