xtensa: don't expect XCHAL_* macros to be constant
Get rid of the assumption that XCHAL_* macros are preprocessor
constants: don't use them in preprocessor conditionals or in static
variable initializers.

bfd/
* elf32-xtensa.c (elf_xtensa_be_plt_entry,
elf_xtensa_le_plt_entry): Add dimension for the ABI to arrays,
keep both windowed and call0 ABI PLT definitions.
(elf_xtensa_create_plt_entry): Use selected ABI to choose upper
elf_xtensa_*_plt_entry endex.
(ELF_MAXPAGESIZE): Fix at minimal supported MMU page size.
gas/
* config/tc-xtensa.c (density_supported, xtensa_fetch_width,
absolute_literals_supported): Leave definitions uninitialized.
(directive_state): Leave entries for directive_density and
directive_absolute_literals initialized to false.
(xg_init_global_config, xtensa_init): New functions.
* config/tc-xtensa.h (TARGET_BYTES_BIG_ENDIAN): Define as 0.
(HOST_SPECIAL_INIT): New definition.
(xtensa_init): New declaration.
