WITHOUT_BINUTILS= based head -r356427 FreeBSD context: x11-toolkits/qt5-gui build fails in poudriere: unable to execute command: Executable "as" doesn't exist!

[Mark Millard]

[Ports was at -r528828 so this did not check
-r531601 update to 5.14.2 of Qt5.]

This is based on worlds built via WITHOUT_BINUTILS= .

I was checking to see how things are for "[o]ne of the goals of
this process [ExternalGCC] is to deprecate and remove the old
GCC 4.2.1 and binutils 2.17.50 in the base system".

On an aarch64 machine with head -r356427 that has a armv7
world directory tree for the same version that is set up
for poudriere-devel use, I attempted to build ports but I
ran into the following for the indirectly needed qt5-qui
(I un-interlaced the output for easier reading):

This suggests that a dependency on a ports binutils is needed
and use of it is needed to keep this building when binutils
2.17.50 is absent in head.
