In an experiment with building some arm ports via poudriere
cross building on amd64 I got the following. It appears that
clang does not handle all the assembler notation and a
different assembler might need to be used for x11/pixman .
(The x11/pixman usage is indirect from having specified
x11/lumina and x11/xscreensaver ).

(I've omitted much later material continuing to reject notation.)
(A variant build without the -mcpu=3Dcortex-a7 usage got the same.)
The context for the above is from a
poudriere/qemu-user-static/native_xtools based cross build from
amd64:
poudriere jail -c -j zrFBSDx64CjailArmV7 -a arm.armv6 -x -m null -M =
/usr/obj/DESTDIRs/clang-armv7-installworld-poud -S /usr/src -v =
12.0-CURRENT
poudriere bulk -j zrFBSDx64CjailArmV7 -w -f /root/armv7-origins.txt
The -x use was enabled for -m null via:
/usr/local/share/poudriere/jail.sh having a "build_native_xtools"
added:

I've also had trouble in some contexts with where bad.port.mk
uses ${UNAME} (empty string results) and so have forced the
