Support aligning text section from odd addresses

Previously, the alignment directives were not correctly supported
in the text section when current alignment was only 1 byte (i.e.,
when the address was odd).  Since there are no 1-byte instructions
in RISC-V, this patch resolves the bug by writing a zero byte to
obtain 2-byte alignment, at which point a 2-byte NOP can be used
to obtain 4-byte alignment.

Resolves https://github.com/riscv/riscv-gnu-toolchain/issues/205

	* config/tc-riscv.c (riscv_make_nops): Emit 2-byte NOPs.
	(riscv_frag_align_code): Correct frag_align_code arg.
