[PATCH][MSP430] Remove .init/.fini sections from CRT library code

[Jozef Lawrynowicz]

The attached patch remove the .init/.fini sections from crt0/crtn. Detailed
explanation on the changes is in the commit message.

Successfully regtested the GCC/G++ testsuites for msp430-elf using the latest
GCC and binutils. 

The attached "gcc.patch" patch to GCC is required before building. It enables
"initfini_array" (--enable-initfini-array) by default for msp430, and also makes
the crtn.o file an optional part of ENDFILE_SPEC (since this patch removes that
file).
If the attached newlib patch is accepted I will apply "gcc.patch" to GCC.

If the newlib patch is acceptable, I would appreciate if someone would commit it
for me, as I do not have write access.

Thanks,
Jozef
