[PATCH] git-compat-util.h: use apparently more common __sgi macro to detect SGI IRIX

From: Gary V. Vaughan <redacted>

IRIX 6.5.26m does not define the 'sgi' macro, but it does define an '__sgi'
macro.  Since later IRIX versions (6.5.29m) define both macros, and since
an underscore prefixed macro is preferred anyway, use '__sgi' to detect
compilation on SGI IRIX.

Hi Gary,

Here's a resubmit of your patch with an updated commit message.  Since the
__sgi macro seems to be more common than the sgi macro, I modified your
patch to check for only the __sgi macro.  I know Junio suggested checking
for both macros, but I'm the one that Junio was talking about when he made
his comments, and __sgi works for me.

It's such a simple little patch, but still I removed your signed-off-by line
since I modified the patch, and I am not you.  Please do reply to this message
with a signed-off-by if you sign off on the patch.  Junio will add it to the
patch when he applies the it.
