following changes remove all uses of alloca from BFD.

cruft (like the #pragma alloca for AIX).

means checking for being out of memory can't work right. The
following changes remove all uses of alloca from BFD.

ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
sunos.c: Replace alloca with malloc and appropriate error checking and
freeing.
