As a general question: in lieu of grafting INIT_ARRAY_SECTION_ASM_OP into
GCC's target/ABI neutral sources, might it be preferable to extend a
target's ability to utilize INIT_SECTION_ASM_OP control the definition of
any behavior, symbol names, etc., as may be required to enable a target to
support EABI, or any other target specific initialization conventions as may
be desired?
