Set bfd_com_section on all common syms.

[Alan Modra]

I missed some places that deal with common syms and need a segment
to be set.

	* config/tc-ppc.c (ppc_pe_comm): Set bfd_com_section segment.
	* config/tc-alpha.c (s_alpha_comm): Likewise.  Also, remove
	redundant check.
	* read.c (s_lsym): Remove non-BFD assembler sym handling.
