These changes separate PA-SOM support from PA-ELF support.
A sun4-x-hppaosf assembler can now be built.
Include <stdlib.h> and <unistd.h>. Do not define malloc or free.
* hppa.c (hppa_core_file_p): Provide a temporary dummy routine
for HOST_HPPABSD.
* bfd/hosts/hppabsd.h: Fix declarations of malloc and free.
* bfd/libhppa.h: Include sysdep here. Conditionalize
includes based on HOST_HPPAHPUX or HOST_HPPABSD.
Provide definitions for MAXCOMLEN and _PA_RISC_ID suitable
for BSD.
* hppa.c: Use this for both HPUX & BSD.
* targets.c: Enable hppa_vec for both HPUX & BSD.
* config/hppabsd.mt: TDEFINES => TDEFAULTS.
* hosts/hppabsd.h: #define HOST_HPPABSD.
* targets.c, config/i960-bout.mt, hosts/*: added
HOST_BIG_ENDIAN_DEFAULT_VECTOR and
HOST_LITTLE_ENDIAN_DEFAULT_VECTOR because bout archive format
depends on the endianness of the host. Added #define
HOST_BIG_ENDIAN_P and #undef HOST_BIG_ENDIAN_P to a number of
configuration files in hosts/ (it was already in some).
