Re: Orphan output section with multiple input sections

Re: Orphan output section with multiple input sections

The last patch missed handling the case where the ideal place to put
an orphan was after a non-existent output section statement, as can
happen when not using the builtin linker scripts.  This patch uses the
updated flags for that case too, and extends the support to mmo and pe.

	PR ld/19162
	* emultempl/elf32.em (gld${EMULATION_NAME}_place_orphan): Pass
	updated flags to lang_output_section_find_by_flags.
	* emultempl/mmo.em (mmo_place_orphan): Merge flags for any
	other input sections that might match a new output section to
	decide placement.
	* emultempl/pe.em (gld_${EMULATION_NAME}_place_orphan): Likewise.
	* emultempl/pep.em (gld_${EMULATION_NAME}_place_orphan): Likewise.
	* ldlang.c (lang_output_section_find_by_flags): Add sec_flags param.
	* ldlang.h (lang_output_section_find_by_flags): Update prototype.
