Include dummy ASM_END definition in mpn/asm-defs.m4 for PowerPC

[David Chau]

For both -O -S and -O -S -fPIC, the compiler generates:

getlocaladdr:
	lis	r3, %hiadj(localvar)
	addi	r3, r3, %lo(localvar)
	blr

getglobaladdr:
	lis	r3, %hiadj(globalvar)
	addi	r3, r3, %lo(globalvar)
	blr

Also, looking at mode1o.asm, it looks like it chooses between table-lookup
via LEA and computing the number arithmetically. If we can't get a generic
version of LEA for PPC, maybe you could have it default to the arithmetic
version.
