x11-toolkits/qt5-gui build on/for Cortex-A7 ( head -r356109 ) failed with: unable to execute command: Executable "as" doesn't exist

Sun Dec 29 06:03:10 UTC 2019

Is system-clang 9.0.1 supposed to implicitly try to use
/usr/local/bin/as ? It does for this context . . .

Note the -fno-integrated-as use in the later quoted log material.

I'll also note that an experiment via -### shows that system-clang
9.0.1 then uses a command like (from a very simple example test):

"/usr/local/bin/as" "-mfpu=vfp" "-meabi=5" "-o" "a.o" "/tmp/a-14ae2e.s"

and that in turn presumes that devel/binutils has provided
/usr/local/bin/as .

That in turn means that, for ports-mgmt/poudriere-devel to
work for x11-toolkits/qt5-gui ,

BUILD_DEPENDS=  at-spi2-core>=0:accessibility/at-spi2-core \
                ${LOCALBASE}/include/linux/input.h:devel/evdev-proto \
                ${LOCALBASE}/include/vulkan/vulkan.h:devel/vulkan-headers

would need to also include (or the @native explicita-flavor variant):

${LOCALBASE}/bin/as:devel/binutils

HOWEVER, I'm not sure if the implicit use of /usr/local/bin/as
is intentional or not for system-clang.

The failure report (1st error only, there were more):
