phdrs and excluded sections

phdrs and excluded sections

[Alan Modra]

When using PHDRS in a linker script, the assignment of sections to
segments happens before output sections are stripped.  This can result
in linker errors that aren't really warranted.

	PR 1042
	* elf.c (assign_file_positions_for_segments): Remove excluded
	sections from the segment map.
