And the undesignated symbols are...? Is the issue recent?

I suppose the symbols are from GLIBCXX_3.4.16. If (as has been the case
for Solaris until very recently) the HP-PA Linux baselines were only
updated immediately before a minor (X.Y.0) release, the only contain
symbols up to GLIBCXX_3.4.15, which was how 4.6.0 was released.
check_abi (incorrectly IMO) flags GLIBCXX_3.4.16 symbols as
incompatible.

Indeed (sorry) the "troublesome" (ie, leading to FAIL) symbols seem the <added>
ones, on x86_64-linux too we have two <undesignated> and no FAIL.

(by the way, while we are at it, on x86_64-linux I also currently have 1
<added>, no FAIL, when building --enable-libstdcxx-time=rt, I suppose it's
fine)

Attached is the symbol diff. The undesignated symbols are:
2 undesignated symbols
0
_ZSt11__once_call
std::__once_call
version status: compatible
GLIBCXX_3.4.11
type: tls
type size: 4
status: undesignated
1
_ZSt15__once_callable
std::__once_callable
version status: compatible
GLIBCXX_3.4.11
type: tls
type size: 4
status: undesignated

Hey all. Undesignated are optionally-added symbols (like tls) that are
configure or platform dependant and so are not set into the baselines. This is
new.
They are not FAIL. It's the incompatible symbols that are making this FAIL.
As of the fix for 52191, abi_check assumes that baseline_symbols.txt file is
current as per the last release. For the 4.7.0 release, this means:
Current in 4.7.0:
GLIBCXX_3.4.17, CXXABI_1.3.6, CXXABI_TM_1
It seems as if HPPA-linux baselines are in no way current. Looking back at the
repository, the last time this file was updated for hppa was jan 2009.
(gcc-4.3/4.4 ish)
>From your diff, hppa-linux is adding into:
+OBJECT:0:CXXABI_1.3.3
+OBJECT:0:CXXABI_1.3.4
+OBJECT:0:CXXABI_1.3.5
+OBJECT:0:CXXABI_1.3.6
GLIBCXX_3.4.11
GLIBCXX_3.4.12
GLIBCXX_3.4.13
GLIBCXX_3.4.14
GLIBCXX_3.4.15
GLIBCXX_3.4.16
GLIBCXX_3.4.17
Which is every release post 4.3.x, starting with 4.4. So, this could make
sense.
None of the symbol additions for hppa-linux diverge from x86-linux in name or
version, so this seems ok to me if you just want to update the hppa-linux
baselines to 4.7.0 exports.
Once you update the trunk hppa baselines, abi_check will stop failing.
