[GOLD] --gc-sections deletes section referenced from .eh_frame

[Alan Modra]

Powerpc 32-bit happens to use a section that doesn't match any of
the existing hacks in is_section_name_included().  Details in the PR.
OK to apply?

	PR gold/14727
	* object.cc (Relobj::is_section_name_included): Also match
	.sdata personality section.
