[RFA/PATCH] Fix recognition of NT_PRXFREG notes

[Mark Kettenis <kettenis@chello.nl>]

After Alan's 2002-06-25 change some tests in GDB's testsuite have been
failing on Linux.  Turns out the current code that reads NT_PRXFREG
notes expects note->namesz to be 5, but with the trailing 0, the
length of "LINUX" is 6.  Turns out the Linux kernel doesn't include
the trailing 0 in the name size.  According to the Systemm V ABI the
trailing 0 should be included, so Alan's change is correct and Linux
is wrong here.  But since changing the Linux kernel isn't going to
happen overnight, I propose the attached fix.

Ok to check this in?
