New sourceware binutils-gentoo-sparc builders

[Mark Wielaard]

Hi,

Thanks to Sam James, the Gentoo Foundation and OSUOSL
builder.sourceware.org now has a gentoo-sparc worker [1]
which runs binutils CI [2] and try [3] builders.

It seems in good shape with only two unexpected failures for
the ld tests:

   	 === gas Summary ===

# of expected passes		365
# of unsupported tests		7


     === binutils Summary ===

# of expected passes		253
# of unsupported tests		6

     === libsframe Summary ===

# of expected passes		23

     === libctf Summary ===

# of expected passes		18

     === ld Summary ===

# of expected passes		1596
# of unexpected failures	2
# of expected failures		26
# of untested testcases		1
# of unsupported tests		157

The two ld FAILS are:

Running: tmpdir/pr26391-5 > tmpdir/pr26391-5.out
child killed: illegal instruction
FAIL: Run pr26391-5

Running: tmpdir/pr26391-6 > tmpdir/pr26391-6.out
child killed: illegal instruction
FAIL: Run pr26391-6

Hopefully Sam can help figure out what caused the crash.

Cheers,

Mark

I've filed a bug for this at https://sourceware.org/bugzilla/show_bug.cgi?id=30002,
but in doing so, I ended up finding some interesting bits from the last few years.

glaubitz from Debian bisected the issue at https://sourceware.org/bugzilla/show_bug.cgi?id=26391#c10
and came up with:
```
496afd17055aeb7d8f45e01715c475664f2b73bd is the first bad commit
commit 496afd17055aeb7d8f45e01715c475664f2b73bd
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Sat Sep 12 05:37:30 2020 -0700

elf: Add -z unique-symbol to avoid duplicated local symbol names
```

but H.J Lu couldn't immediately find a reason why it would happen on
sparc, and then it looks like the issue was forgotten about.

Nice. Would it be possible to add gcc and glibc there as well?

I completely forgot about this bug. I had to reread the bug report to make sure
I actually did the bisect ;-).

Yeah, that's no problem at all. The box isn't busy enough right now ;)
