powerpc64 system-clang-8 based context: x11-toolkits/qt5-declarative fails to build in poudriere: /usr/local/lib/qt5/bin/qlalr segmentation faults in std::type_info::~type_info() () from /usr/local/lib/gcc8/libstdc++.so.6

[I adjusted the Subject line to give more context.]
[/usr/local/lib/qt5/bin/qlalr and /usr/local/lib/qt5/libQt5Core.so.5
overall use each of the following (somewhat indirectly) in my
system-clang-8-based powerpc64 context:
/usr/local/lib/gcc8/libstdc++.so.6
/usr/lib/libc++.so.1
/lib/libcxxrt.so.1

Remembering that my context is system-clang-8 based
world on powerpc64, not gcc 4.2.1 . . .
/usr/ports/Mk/Uses/qt-dist.mk has:
. if ${ARCH:Mmips*} || ${ARCH:Mpowerpc*} || ${ARCH} == sparc64
_EXTRA_PATCHES_QT5+= ${PORTSDIR}/devel/${_QT_RELNAME}/files/extra-patch-mkspecs_common_g++-base.conf \

USE_GCC= yes
. endif
That is no matter what the system compiler is for powerpc64.
This lead to the below mixing of libstdc++.so.6 and libc++/libcxxrt . . .
qlalr indicates use of both libstdc++ and libc++/libcxxrt :
# ldd /usr/local/lib/qt5/bin/qlalr
/usr/local/lib/qt5/bin/qlalr:
libQt5Core.so.5 => /usr/local/lib/qt5/libQt5Core.so.5 (0x8100b1000)

libintl.so.8 => /usr/local/lib/libintl.so.8 (0x811b45000)
And so does libQt5Core.so.5 :
# ldd /usr/local/lib/qt5/libQt5Core.so.5
/usr/local/lib/qt5/libQt5Core.so.5:
libkvm.so.7 => /lib/libkvm.so.7 (0x8113ad000)
libprocstat.so.1 => /usr/lib/libprocstat.so.1 (0x8113d2000)

libz.so.6 => /lib/libz.so.6 (0x811402000)
libicui18n.so.64 => /usr/local/lib/libicui18n.so.64 (0x81142e000)
libicuuc.so.64 => /usr/local/lib/libicuuc.so.64 (0x81183d000)
libpcre2-16.so.0 => /usr/local/lib/libpcre2-16.so.0 (0x811aaf000)
libglib-2.0.so.0 => /usr/local/lib/libglib-2.0.so.0 (0x811b5f000)
libstdc++.so.6 => /usr/local/lib/gcc8/libstdc++.so.6 (0x811cbf000)

libthr.so.3 => /lib/libthr.so.3 (0x811f78000)
libc.so.7 => /lib/libc.so.7 (0x810071000)
libelf.so.2 => /lib/libelf.so.2 (0x811fc1000)
libutil.so.9 => /lib/libutil.so.9 (0x811fee000)
libicudata.so.64 => /usr/local/lib/libicudata.so.64 (0x812018000)
libc++.so.1 => /usr/lib/libc++.so.1 (0x812029000)

libintl.so.8 => /usr/local/lib/libintl.so.8 (0x81232f000)
It appears that the libc++/libcxxrt use comes from:
# ldd /usr/local/lib/libicui18n.so.64
/usr/local/lib/libicui18n.so.64:
libicuuc.so.64 => /usr/local/lib/libicuuc.so.64 (0x81100f000)
