elf.5: EI_BRAND is not exist in Linux

elf.5: EI_BRAND is not exist in Linux

[Yuri Kozlov]

Hello.

>From elf.5:
 e_ident     This array of bytes specifies to interpret the file, ...
    EI_BRAND    Start of architecture identification.

Value for EI_BRAND is not defined in the linux/elf.h (and gabi too).
Maybe add some comment, that is for *BSD only?

Hey Mike,

You've done a patch or two to the elf.5 page in the past. Are you able
to comment on the below? I confirmed Yuri's statement: EI_BRAND isn't
in glibc 2.11 source.

Cheers,

Michael

not being the glibc source isnt terribly important imo (since there are a lot 
of things glibc's elf.h doesnt define), but the fact it isnt in the gabi as 
Yuri notes seems pretty important:
http://www.sco.com/developers/gabi/latest/ch4.eheader.html

whether it be marked as non-standard (and then we research what random OSes 
actually define it) or simply drop it, either makes sense to me.  the latter 
is obviously less work :).

Okay -- I simply removed the test, as shown in the patch below. Okay?
