[rl78] avoid line separator characters

[DJ Delorie]

GAS's line sep character is changing.  This patch avoids using it
completely, to avoid release dependencies as much as possible.
Applied.

	* libc/machine/rl78/setjmp.S: Convert from CPP macros to GAS
	macros, to avoid dependence on the line separation character.

	* rl78/crt0.S (_interrupt_vector_table): Convert from CPP macros
	to GAS macros, to avoid dependence on the line separation
	character.
