Linux fixes [PATCH]

[Shaun Jackman]

I found the following patches necessary to compile newlib for
i386-linux, In addition, dl-load.c is not compiling because it cannot
find the symbol __RTLD_DLOPEN, which should be defined by dlfcn.h.

Cheers,
Shaun

	* newlib/libc/posix/scandir.c (scandir): Update the function
	prototype to match the header.
	* newlib/libc/sys/linux/linuxthreads/bits/libc-lock.h: Remove an
	extraneous #endif.
	* newlib/libc/sys/linux/sys/lock.h: Do not include
	machine/weakalias.h, since it's not used by this file.
