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.

cruft (like the #pragma alloca for AIX).
In addition to that problem, the C alloca calls xmalloc, which
means checking for being out of memory can't work right. The
following changes remove all uses of alloca from BFD.
* hosts/solaris2.h: Remove alloca cruft.
* som.c: Replace alloca with a fixed size auto array.

Replace alloca with malloc and appropriate error checking and
freeing.
