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=cortex-a7 usage got the same.)
