For PE format files, the base relocation table is necessary if the image is loaded at a different image base than specified in the PE header. This patch provides a new option --enable-reloc-section to force the generation of this section.
* emultempl/pe.em: Add new option --enable-reloc-section.
* emultempl/pep.em: Likewise.
* ld.texi: Document --enable-reloc-section.
* pe-dll.c (pe_dll_build_sections): Use pe_dll_enable_reloc_section.
(pe_dll_fill_sections): Simplify by calling pe_exe_fill_sections.
* pe-dll.h: Add extern declaration of option flag.
* pep-dll.c (pe_dll_enable_reloc_section):
Add alias define for pep_dll_enable_reloc_section.
* pep-dll.h: Add extern declaration of option flag.
