* sysdeps/unix/sysv/linux/ldsodefs.h (VALID_ELF_HEADER)
(VALID_ELF_OSABI, VALID_ELF_ABIVERSION, MORE_ELF_HEADER_DATA):
Move macros to...
* sysdeps/gnu/ldsodefs.h: ... this new file.
* sysdeps/unix/sysv/linux/ldsodefs.h (VALID_ELF_OSABI)
(VALID_ELF_ABIVERSION, MORE_ELF_HEADER_DATA): Use ELFOSABI_GNU
instead of ELFOSABI_LINUX.
