ld: Parse linker script only once

Parsing linker script twice caused

FAIL: ld-plugin/lto-3r
FAIL: ld-plugin/lto-5r
FAIL: PR ld/19317 (2)

for x86_64-w64-mingw32 with the linker error:

./ld-new:built in linker script:27 assignment to location counter invalid outside of SECTIONS

ldscripts/i386pep.xr has

 24   .rdata  :
 25   {
 26     *(.rdata)
 27     . = ALIGN(4);
 28     /* .ctors & .dtors */
 29     /* .CRT */
 30     /* ___crt_xl_end__ is defined in the TLS Directory support code */
 31   }

Remove ld_parse_linker_script to parse linker script only once.

	* ldlang.c (cmdline_emit_object_only_section): Don't call
	ld_parse_linker_script.
	* ldmain.c (main): Fold ld_parse_linker_script.
	(ld_parse_linker_script): Removed.
