H.J. Lu 5fe2850dd9 Set DF_1_PIE in gld${EMULATION_NAME}_after_parse
We can't add OPTION_PIE to gld${EMULATION_NAME}_handle_option since
it has been handled in parse_args in lexsup.c.  This patch moves
setting DF_1_PIE to gld${EMULATION_NAME}_after_parse.

ld/

	* emultempl/alphaelf.em (alpha_after_parse): Call
	gld${EMULATION_NAME}_after_parse instead of
	after_parse_default.
	* emultempl/cr16elf.em (cr16elf_after_parse): Likewise.
	* emultempl/crxelf.em (crxelf_after_parse); Likewise.
	* emultempl/hppaelf.em (hppaelf_after_parse): Likewise.
	* emultempl/mipself.em (mips_after_parse): Likewise.
	* emultempl/nds32elf.em (nds32_elf_after_parse): Likewise.
	* emultempl/elf32.em: Don't include ldlex.h.
	(gld${EMULATION_NAME}_after_parse): New function.
	(gld${EMULATION_NAME}_handle_option) [GENERATE_PIE_SCRIPT]
	<OPTION_PIE>: Removed.
	(ld_${EMULATION_NAME}_emulation): Replace after_parse_default
	with gld${EMULATION_NAME}_after_parse.
	* emultempl/ia64elf.em (gld${EMULATION_NAME}_after_parse):
	Renamed to ...
	(ia64elf_after_parse): This.  Call
	gld${EMULATION_NAME}_after_parse instead of after_parse_default.
	(LDEMUL_AFTER_PARSE): Replace gld${EMULATION_NAME}_after_parse
	with ia64elf_after_parse.

ld/testsuite/

	* ld-elf/pie.d: New test.
