The stor-layout change causes the compiler to emit an error if it
encounters an array whose size can not be expressed in a size_t.
The second change just fixes up -p and -pg so that you can build
and link things with -p and -pg. Nothing too radical. Jason and I
had pondered moving this change into the generic elfos.h, but aren't
going to do that at this time.
Bootstrapped x86-linux. No regressions.
* stor-layout.c (layout_type): Complain if an array's size can
not be represented in a size_t.
* config/h8300/elf.h (ENDFILE_SPEC, STARTFILE_SPEC): Define.
