binutils/elf2flt: Add CUSTOM version, CUSTOM_LOCATION config options, GetCustom

CUSTOM_LOCATION config options only presented in menuconfig if component
CUSTOM version selected.

Change elf2flt CT_ELF2FLT_VERSION from 'head' to 'cvs' if cvs selected in config

Also remove hardcoded 'cvs-' from elf2flt component name, used in CT_Extract,
CT_Patch and as the CT_SRC_DIR location for the configure stage.
