Fix NOSHAREDLIBS in configure.in, and check for -1 from sbrk.

[Matt Birkholz]

I configured kaffe-0.9.2 with --enable-staticlib but the build died looking
for kaffe_native:
	gcc -g -O2  -I. -I./../kaffevm -I../../config -I./../../config -I../../include -I./../../include -o kaffe main.o -L../kaffevm -lkaffevm  -L../../packages/tjwassoc.co.uk/APIcore/lib -lkaffe_native -L../../packages/tjwassoc.co.uk/APInet/lib -lkaffe_net -L../../packages/tjwassoc.co.uk/APIzip/lib -lkaffe_zip  -L/usr/X11R6/lib -lX11 -lkaffevm -lm -lc 
	ld: cannot open -lkaffe_native: No such file or directory
I had to fix configure.  A similar patch for configure.in might be:

A somewhat static kaffe allowed me to see why I was getting this:

    Cannot find essential class 'Object' in class library ... aborting.

In the debugger, kaffe goes comatose.  An interrupt finds it in pagealloc
getting -1 from sbrk.  (My wife was running Netscape too.) Do not ask me
how that leads to "Cannot find essential..." and I will not ask why
gc-mem.c contains a call to sbrk but does not check for the exceptional
return value -1.

The reason I say my kaffe is "somewhat static" is because of this:

	ldd kaffe
		libX11.so.6 => /usr/X11R6/lib/libX11.so.6
		libm.so.5 => /lib/libm.so.5
		libc.so.5 => /lib/libc.so.5

-- not exactly what I expected.
