dynamicly linked executables.)
subspaces too when writing executables. Never request a negative
bss size. Fixes some problems with demand paged executables,
still having problems with pure executables and shared executables.
containing all the private section information which needs
to be copied from input section to output section during

exec_flags fields.

elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
returns NULL, it is not an error. It's possible that some of
these checks are not necessary (because the size can never be
zero), but putting in the checks is the conservative thing to do
in light of the fact that some of these malloc calls replaced
unchecked alloca calls, in which a zero argument would work fine.
