* sysdeps/powerpc/elf/sysdep.h: Remove this file, because it overrides
the more-specific unix/sysv/linux/powerpc file and breaks everything.
* sysdeps/powerpc/sysdep.h (ALIGNARG, ASM_TYPE_DIRECTIVE,
ASM_SIZE_DIRECTIVE, CALL_MCOUNT, ENTRY, EALIGN, DO_CALL, JUMPTARGET,
PSEUDO, PSEUDO_RET, PSEUDO_END, L, C_TEXT): These macros moved here
here, put under [__ELF__].
