EI_OSABI in the ELF header on GNU/Linux systems

[Richard Sanders]

I noticed that the EI_OSABI field in the e_ident member of the ELF
header (offset 8) is being set to 0x00 rather than 0x03.  Is this just
an oversight or is it intended?  I dug around in the elf.h header file
and found ELFOSABI_SYSV defined as 0x00, which is (mostly) correct if
rather vague.  Shouldn't the library be using ELFOSABI_LINUX which is
defined as 0x03 and was intended for GNU/Linux?

Here is a snapshot of the System V ABI that defines these values:
