stage-qa ignores non-striped *.so

Hi,

Recently Q/A tests (stage-qa) started to ignore non-striped *.so 
libraries for me.
Explicitly checked that script Mk/Scripts/qa.sh is called.

I have:
DEVELOPER=yes
in files:
/etc/make.conf
/usr/local/etc/poudriere.d/make.conf

For example:

cd security/p5-Crypt-Argon2
comment out STRIP_CMD from Makefile:

#post-install:
#       ${STRIP_CMD} 
${STAGEDIR}${PREFIX}/${SITE_ARCH_REL}/auto/Crypt/Argon2/Argon2.so

 > make -V DEVELOPER
yes
 > make -V WITH_DEBUG
(is empty)
 > make clean stage stage-qa
====> Running Q/A tests (stage-qa)
(is empty)

And NO usual warning is signaled in a way as it has been happening before:

Warning: 'lib/perl5/site_perl/mach/5.42/auto/Crypt/Argon2/Argon2.so' is not
stripped consider trying INSTALL_TARGET=install-strip or using ${STRIP_CMD}

Building in "poudriere testport" also does not signal this warning.

Please advice me how to restore the usual operation of Q/A tests (stage-qa).

Regards, Sergei
